I would say that this would not be suitable for certain games. Such as those which need fast communication with each other (if they don’t have discord or don’t know each other) This would also not be suitable for games which need alot of in game chatting (e.g. Trade Hangout) and those which use chat admin commands.
But this would be suitable for most games since the games which are not suitable for this module is not alot.
Great work! 
Well, if you consider that a bot joins the game for miliseconds, then leave, and that if you have a good internet connection this takes seconds, you won a point 
iirc they disabled requiring private 3rd-party modules by asset ID for security reasons. It should still work if the module is open-source or you created the module.
This helps so much, thank you for doing this!
Yes! That was the thing I was looking for, thanks!
Unless the developer turns it off, the module is built to save. Meaning players do it once and don’t have to do it again (until it expires).
Im sure they can play the game, they just can’t chat in the game.
In that case, this will depends on the game:
Is the game a roleplay game where you need the chat? Then you still will ruin the fun
Is the game a game typ, that dosen‘t requires any special communication with other players, then it will be annoying, but is better as nothing. Still, aside singleplayergames, I don‘t believe that on Roblox you will many games that, are multiplayer, but don‘t require to talk to other players. If you have a multiplayer, then you really need to talk with others (as exception a few games types like Arsenal, where you don‘t need to talk at all)
Really cool idea, i’ll be sure to insert it into my game when I have the time!
Wow! This is amazing! I have recommended this service to my friends. They tried it, and they loved it! Definitely recommend this product/service to others seeing this post. 
Keep up the good work!
You can just use a ML (machine learning) and with neural network to figure out the message is either a malicious message or not, and it’s much reliable, as you don’t need to add new stuff to the network, which you must add new challenges for the captcha if they implemented something that auto-solves your captcha system.
Of course, the ML won’t just determine either it’s malicious or not based on just the link, it should be based on the context.
You don’t even need a captcha as these bots aren’t anything special. Just to have a button that enables chat at the start of the game will probably defeat 99% of them.
Sure, you can do that currently. But bots are already adapting as more games implement simple solutions. As I’ve said earlier, people who run bots will go to great lengths earn a buck or put a message out. So what works now may not work a few months from now.
why not just add a filter for the word {System} and add a list of links that are going around (you can find a lot just by playing bad business; the bots love it there)
edit: actually 4D_X makes a good point; you can easily stop them with just adding something to interrupt chatting for the first like minute. once they chat they leave so if they join, try to chat, then leave, the message won’t go through, obviously, because you can’t chat for the first 60 seconds of joining
Sure, some might implement solutions, but only if they are targeting a specific game. These bots are most likely not injecting any code to simply chat, and are just emulating keyboard strokes to chat. (pressing “/”, pasting their message, pressing enter, and then moving onto the next server).
I think we should leave this issue to Roblox and just continue to educate players on these types of bots. Something like fingerprinting would help this issue significantly, as these bots aren’t on the Roblox webpage at any time, and just launch Roblox with the bots authentication ticket. Captchas just create work for such a simple thing, and I believe it would discourage users from chatting.
What about setting the Modal in one of the buttons to true?
It’s added and will be live along with some other features in the update.
Current Update Additions:
These features will be live to everyone with the module! We are currently testing to ensure we don’t break any games.
Although that sounds great, it kinda defeats the whole purpose of the service/captcha to prevent these scam bots in the first place.
Something like a captcha is unnecessary for bots that are not that advanced.
The developer can configure the captcha. And in the following updates, developers will be able to track player behavior and only prompt a captcha when necessary. Also, bot developers will continue to innovate their systems. Most bots currently don’t even load much of the client and instead only fire the necessary events to post chat messages.
