For the people asking for auto clickers... Stay away from anything that has an executable lol.

It's trivial to code your own using AHK or Python.

This is what I use, google AHK, set it up, won't take more than a few minutes and it's 100% safe because you know what it's doing:

!m::
while GetKeyState("m")
{
Click
Sleep, 100
}
return

alt+m starts clicking while I hold it. Sleep, 100 is the delay between clicks in micro seconds, so it clicks 10 times a second. I've tried faster speeds but that seems to kick me out. Might be possible to make it a bit faster, can't be bothered to test.
