READ BEFORE USING
Disable your CORS if this does not work. This can be done with an extension. Here's one. This page is 100% guranteed safe (and open source). You probably want to disable the extension outside of this website, though.
I don't take any responsibility for what you do with this.
How this works
Basically, the way most of these ROBLOX bot accounts are set up is that the password is the reverse of the username. For example, if the username is "User", the password is "resU". Pretty clever! There are groups that have thousands of these accounts as well.
The template of username this page looks for in a group is "FirstnameLastnameNN", where NN is a two-digit number. For example, a valid name would be BillGates12.
