Auto Hot Key itself is just a tool.
So it depends on how you use it.
However, I've seen a lot of posts regarding botting with it.
Not necessarily on this site, but just googling the program in general.

If you want a free option, check out Hot Key Net or Octopus.
I believe both are quite decent options, but haven't used either.

HKN seems quite powerful.
And there is fairly decent support levels for it here.
