About scambots

I know how annoying all of those "click every pic where is traffic lights" but please, even one of those before making account (is there? I don't longer remember)

But if there's not, we need on of them. I'm in one server, which is full of bit younger people and there's always one scambot, I just changed all of my passwords everywhere with panic, because I accidentally clicked one of his link instead of one other. 

Thanks
