I don't think this will be failbinned, although I think it should be. It doesn't directly violate any rules or anything but it's extremely abusable on a lot of different servers. Not that autoclickers weren't easy to make before, but this will just give morons access to them.
When this sort of controversial thing is released, (buildbot for example) I always wish people would include a server mod that disables the mode from being used on their server. I know some people are going to write "LOL ITS SUPER EASY TO CIRCUMVENT THAT" so that they can feel intelligent, but that really isn't the point. A lot of abusable scripts can really easily be made by people with little to no talent, but usually not by a complete idiot who might abuse them. However, when they are released on the other hand, basically everyone can get them.
