Introducing the Ban API and Alt Account Detection

Good point, I was specifically referring to the UserRestrictions API though, I guess I just didn’t word that very well.

Yes, Roblox’s system is easier to set up, but doesn’t provide much customization. So at the cost of managing everything yourself instead, you can customize the ban screen however you want. In this case, alt detection would be the only thing I’m missing out on.

Is there a reason on why it still says “Service not live”?

I’m not experiencing any lag…?

I agree with this, but maybe it should be a settings toggle like Allow HTTP service

how it can detect when you are on a alt? good job roblox i really appreciate it!!

i really thought it would ban you from roblox for a day

I find this interesting, but considering the Roblox Community, there will be a bypass for it within 2 days of it being released.

This is so skibidi rizzler update.

If it would be something like that, people could get youtubers or others to join their game and ban them. Easily getting them banned off roblox for a day.

There’s one pro that’s missing and it’s that you won’t even get connected to a server before getting kicked if you use the native API.

To me, this is a huge pro since exploiters have no chance of doing anything nefarious within the few seconds they get before getting kicked with a custom ban system that relies on a yielding datacall. If your game has CharacterAutoLoads they can abuse physics, they can also save a copy of your game, and they can even fire RemoteEvents if you don’t have them safeguarded by making sure the player isn’t banned before letting them access the network.

I’m curious how it detects which are ALT Accounts ?
I Develop with one, and have an Alt Account . for when need testing.

However, I have 2 kids that often play on my cell, when theirs is flat lol
Now they are kids, and also have alt accounts… only they know why… Diff Avatars… who knows.

Now my question is… if one of them get Banned… they will get banned with any alt to that same experience… if I am correct… and now there’s a possibility I would also get banned… seeing they used my device… for that same experience ?

It’s no biggie… since it’s an experience Ban, and not a Roblox one.
I assume there’s no other risk… across the Roblox platform… with them using my cell, while they jump from device to device ?

Well ever since the release of Hyperion I believe roblox has been doing alot of logging and spying lmao. I think roblox records this data such as your HWID, IP and other data points thrn later cross compares them with other accounts to see which match in their database, and if multiple criterion areflagged then it flags it as an alt

Alt Detection is technically possible with a custom ban system, since fingerprinting a device is possible within ROBLOX.
But the identifier won’t last very long (computer reboot changes the data and, if you’re using a hashing algorithm for the data, then the hash too).
ROBLOX’s system will be more permanent, but a custom one can delay rule breakers a LOT. (Espescially when ROBLOX’s alt detection isn’t actually working right now)
But basically you can compare the hash when a player joins with a banned hash and then you can kick anyone with the same hash. (Fetch the data on client, hash it on client, send hash to server using RemoteEvent as soon as they join, kick any player that fires the Remote twice, and now you can compare the hashes)
Suprised those fingerprinting methods aren’t more well known yet.

Doesn’t this issue apply with any ban system? (Espescially the first reason)
Third thing shouldn’t be an issue either, ROBLOX literally starts their own game servers for moderation (From what it looks like)
They’ve got an account with UserId zero in a game server with a JobId “GameSafetyReview” and ban APIs probably won’t work.
Not to mention it’s not really ROBLOX admins that do it, but rather hired moderators that probably don’t have a main account.

Anyone else here still having an issue with :UnbanAsync not working?

Seconding this! As an owner of a game with over 400,000 bans, it pains me that I can’t utilize ban notes at all with the current system since it will fail the ban if the note is filtered. I still will not use ban notes if the filter remains in place but bans do not fail, since most of my ban notes include appeal ticket numbers that would normally be filtered.

If the filter is still in place when my new moderation system goes live, all 400,000 of these banned players will flood my Discord server asking for the reason they were banned. It makes no sense for ban reasons to be force filtered when text labels, kick messages, and every other non-user-generated string value does not require filtering.

for some time i was using my brother’s laptop to play roblox because my pc’s hard drive died
im scared my brother might get banned from some game and since his laptop is logged in my account he might be banned if i troll at some game
(off topic thing : dont store important stuff on your hard drive if you have an ssd save it there espically if your hard drive makes any noise )

Roblox added a feature for developer but their negligence to makes it work for developer is an overlook, you can ban someone with their alt bypassing of adding a filter of unbannable userid because I don’t have access to tell who’s who alt(you can ban the game owner by banning their alt, you can’t tell which alt you got ban from so you have to look for that alt account, if you can’t access your old alt you have to manually unban every of your alt just so you get unban), the fact that the api don’t works in studio make it so that studio is pointless to test so you can’t makes a plugin with this api.
If in-case you got yourself ban the step of getting unban is publishing the game with an unbanasync script of every desired userid which is very manual work, but I do hope roblox makes it easier to manage ban on their app or web.
Super abusable system? 100% yes, they neglected to add a filter for who to not get ban.
You can’t makes a plugin with the api but I manage to makes a version for live game.


For a non scripter you can basically screw them up by banning them, likes what they own the game and you can do that?
Extra edit: Since this feature is live that mean every game with a backdoor can potentially have a huge vulnerability risk against the creator.
