Unfortunately, exploiters are able to bypass this. This is a problem I truly believe Roblox will have to fix!
I like this idea in principle, but I am unfortunately colorblind. As with a large percent of the population, what would be your implementation around this. I can identify images, sure, but colors are a little bit tricky for me and I donât think Iâm a robot

Unfortunately yes, people who are colorblind would have a hard time solving the puzzle. A few people in this thread suggested a multiple choice puzzle or words with missing letters, which I think would be the best alternative
I donât think there is a way of separating an exploiter from a normal person from one click. This system is made to prevent bots, not exploiters. I believe there already are ways to stop exploiters from exploiting.
This is great! I can see how this can help stop most bots from advertising spam links.
For colourblind people, I suggest mking a new puzzle on the V2 CAPTCHA that utilizes the new beta UI corner element. The captcha can have a question like âWhich element is the most/least shaped like a circle?â
Keep up the good work, I expect to see some good updates!

The UI corner is a great alternative for colorblind people, thank you for the idea 
Although, it would be easy to detect because the bots would know exactly what to look for in the Gui (UICorner). If they donât have any form of exploiting however, it would work great
I highly disagree, as a developer I run into many issues such as bots and exploiters, this is an issue for not just certain people, most developers as well. So it is in fact, and issue Roblox could solve by creating better captchas, or limiting the amount of bot accounts created, thank you for your input though!

Iâve seen thousands of bots join and start spamming, giving off that they can run code on the client. If they can then just checking some basic values would allow them to bypass this. I donât think this is the best way to prevent it. I would imagine checking there outfit, name, status, friends and the like to see if there a bot rather than a captcha.
NOTE: I didnât have time to read the ENTIRE thread so if someone has already pointed out a correction for this then feel free to reply!
I seriously, do love the idea. But Iâd love it alot more if it was a little bit more if it was a little simplier? like 
This for me is slightly confusing, because Roblox Lua just isnât understanding. .
Personally I think that captchas are more troublesome to players than the protection from bots they provide. Maybe this thread could be useful? A few methods in there could work, and are less disruptive than a captcha.

Iâm pretty sure you can set how round the UI corner will be and If you put most/least shaped like a square/circle randomy each time then it would be harder for bots
I believe that this is quite useless as competent people like Aris that have made powerful bots are able to bypass this quite easily for their bots. He is able to execute any sort of script on all of the bot clients and hence bypass your security so maybe you should try to protect the RemoteFunction.
The only real way this problem could be solved would be by Roblox themselves. Game developers shouldnât have to worry about problems like bots instead Roblox should secure their platform.
Itâs not entirely useless as most bots are lazily made and probably wonât be hardcoded to bypass it. While some advanced bots will be able to bypass it, most/some of the bots will be stopped. Thatâs better than nothing, isnât it?

This solves nothing, only creates a nuisance for the player. All a user has to do is run a program which reads off of the screen, then use a letter recog neural network and select the color based off of it.

Yeah, I have to say I wouldnât make this a system in my game. If anything Iâd just make a light age system so that the bots have to of least of been created at a later date. Obviously not full proof but at least it doesnât get in the ways of genuine players. It might be considerable if youâd of added, âit only works once per accountâ but then again I could just edit it to do that. But honestly, itâs easily bypassed by exploiters and news flash, a exploiter could in theory still have a bot bypass that. so I wouldnât use this.
That being said if youâre confident this could help you then go for it. I just wouldnât use it as a resource.

But isnât the entire point of this Captcha system that it would stop bots which werenât programmed to enter your game in specific?
What Iâm trying to say is: yes, of course if the bot was programmed to get through this specific Captcha, it would be useless. But, if only your game and a handful of others used this system, who would bother creating custom bots for just these games when there are countless others which arenât protected from generic spam bots?
If exploiters can get in, I wouldnât suggest. Though itâs always helpful towards stopping bots I guess.

Itâs good, but whatâs the reason if you have the Chat enabled before completing the captcha? The bots can still spam in the chat.
Solution: Donât forward chats from accounts younger than X days until they complete a captcha
Second method, will take more time to bypass
