An Update on Automated Action Against Modified Clients

[Update] May 8, 2025

Earlier this year, we shared our high-level plan for the year focused on preventing account farming and exploits. We want to share an update on how we are preventing exploits through automated actions. Starting this week, if we detect that a user is using a modified client, we may take action on that account, up to and including account termination.

Over the past few months, we have been testing and refining multiple layers of automated checks to detect when people run modified Roblox applications. “Modified clients” are custom versions of the Roblox application binary downloaded from third-party websites or running instances of the official version of Roblox modified by external tools at runtime. We’ve focused on modified binaries as these are common methods bad actors use to cheat and exploit on Roblox or steal account information. Our Community Standards prohibit their usage (Evading Safety and Security Systems).

During The Hunt: Mega Edition, we used this safety system to ban accounts we detected running modified applications. This was a highly effective tool to prevent exploits and keep The Hunt fair and fun for all. We are now rolling it out full-time for all users and all experiences.

Ensure you are using the official Roblox version

To ensure you’re not running a modified version of Roblox, please download Roblox from an official source (such as roblox.com, the App Store, or Google Play) and do not run any software on your computer that claims to modify Roblox in any way.

If you believe our systems made a mistake, you can appeal through the Violations and Appeals page.

What’s next

We are committed to making Roblox the most trusted gaming platform in the world and believe preventing exploits is an important step. We plan to share more information soon about our other efforts to keep Roblox accounts safe and secure.

Please let us know if you have any feedback or questions.

FAQ

Are we allowed to test our anti-cheat systems by using exploits?

  • We view cheating and exploiting as a platform issue. Our ideal world would be that creators don’t have to worry about this problem, and that we focus on solving it for you. Server Authority (apply for early access here) will be a significant tool to reduce the exploit surface in your experiences. However, we understand the importance of creators needing to test and ensure their anti-cheat systems are robust. While we do not ever encourage running modified clients, as exploit software can contain malware that jeopardizes the security of your system, steals your account information, and/or more, we hear your feedback and will make a change.

    If you’re in a group that owns a given experience, you will not receive consequences if we detect you using a modified client in that experience. If you use someone else’s experience, you will receive consequences. We will post an update here when we make this change. Be aware that until then, we will take action against all users we detect using modified clients. If you believe our systems made a mistake, you can appeal through the Violations and Appeals.

Are you removing Linux support with this change?

  • While we don’t officially support Linux, we want to be clear that we never intentionally seek to break it, as we recognize there’s a passionate community of Linux users who want to see Roblox running on Linux.

    These changes are primarily aimed at enhancing platform security and shouldn’t directly affect whether Roblox works on Linux through tools like Sober. However, we can’t guarantee that third-party software will work or continue to work as we make changes to Roblox.

Does this affect bootstrapping applications like Bloxstrap?

  • These changes shouldn’t affect Bloxstrap right now as it does not modify the client binary. However, please keep in mind that we don’t officially support any third-party software like Bloxstrap. Because we don’t control these programs, we can’t guarantee they’ll remain compatible with Roblox.

Does this affect tools that allow you to run multiple clients on the same machine such as ones that remove the client’s “window” cap or tools like Multiple Games?

  • If the method you are using to run multiple clients does not modify the client binary, then this change will not impact your workflow. If it modifies the binary, then right now this will trigger these consequences but after we make the change described in Anti-Cheat Testing, it will not when testing experiences you own.

    While we do not officially support running multiple player clients simultaneously, we noted your feedback around the value in running multiple clients for testing and development, and we will investigate providing an officially-supported solution.

What if I’m using an analytics tool or external tool that communicates with Roblox via OAuth?

  • Analytics tools, OAuth, and other tools that use official mechanisms to communicate with Roblox systems and services will not be impacted by this change. This policy targets tools that modify the client application code.

As a creator, how will this impact my game?

  • If your game experiences exploits and cheats, you should see a reduction in the number of users using exploits.

So I suppose we are still not allowed to exploit our own games? What a fascinating world, where we have to patch exploits but risk being banned if we dare try to replicate them using a hacked client.

Does this affect tools like “Multiple Games”? It’s a pretty important part of my workflow for testing networking outside of studio otherwise I have to pester one of my friends to come help me

Does this affect applications like bloxstrap? Im confused

I wonder how long this will stop exploiters for.

My main concern is whether or not this will affect Bloxstrap.

no, launcher != modded client. you’re safe.

So, is it joever for the Linux users patching the Android binary somehow (I don’t know the details)? Please tell us this will actually solve exploits for good… because I’ve still been working on exploit detection stuff for the years we’ve had no Linux functionality…

Bloxstrap is a downloader for the client and does not modify it. I would never expect Bloxstrap to be affected since it has nothing to do with running the client.

I sometimes remove the client’s “window” cap so that I can run multiple clients on the same machine. This is useful when debugging networking problems in my games. Will this be affected?

I’m interested to know if there will be an official roblox-backed statement about tools such as bloxstraplabs/bloxstrap. Currently there is a lot of misinformation going around online that may need to be cleared up. (Outside of a devforum reply by a staff member.)

Well since i has uninstall fishtrap, you think this update will affect bloxstrap and fishtrap? i just asking

it does kinda feel unfair that roblox has had higher success rates blocking good-meaning linux users from the platform rather than exploiters and yet they still refuse to even think about adding engine/client/studio support. unacceptable.

There is no correlation that this is specifically targeting Linux users.

No, of course not, Bloxstrap does not directly modify the client, Roblox staff members have stated before that it isn’t against the terms of service at all.

Anecdotal evidence as a guy who maintains a popular OSS tool: Linux users are a vast minority of users but they’re very loud and have a lot of problems with their systems that they expect you to help with. I don’t imagine Roblox considers it worthwhile for their business to support Linux given how much work it’d take and how few paying customers they’d get.

In terms of hating you guys I don’t think it’s hate, I just think it’s apathy because they don’t care about having Linux users.

yes, there is. during the hunt, due to the increased protections using clients like sober was blocked temporarily. because they are being put into place permanently now, we are once again being blocked from playing the game.

What happens if someone has hardware memory errors? I need to fix my pc as it currently has memory errors, and I’ve noticed that Roblox would just close sometimes (no crash window no nothing), which I assume is caused by my memory errors, but I’m wondering if it’s the anti cheat detecting it

I don’t think anyone expected Sober to stay for long, especially with how many measures Roblox is starting to take… I for one did expect this coming from a mile away, hence my current predicament of staying on Windows.

The Sober block was introduced by the Sober maintainers themselves to ensure there were not any potential ban waves or triggers that could be caused by Sober during the event, you could still play under applications like Waydroid just fine (which is what I did)
This post talks about “modified clients” and not running the client in unofficially supported environments.

Do keep in mind that running Roblox inside of a virtual machine is still officially supported by Roblox and is something I’d recommend as it’s pretty simple to do with a few commands and tools.
