You could think outside of the box here... If we get enough signs against these websites and explain our situation, something will happen. I mean... I don't know what is blocking you from think AGAINST the fact that bots are an illness in this game or every game.
Either way I think we can change this situation with our own hands, at least there are people here willing for this change.
Anyway... If there is no business laws that these websites are breaking, then with enough people against one deed a new law arise.
And for the last don't underestimate what people can do together.
