And by the way I have seen people talking to their alts in the same thread quoting their own posts and speaking as if they were 2 different persons. There are some real nut jobs on this forum and before the whole thing goes to shit something radical must be done. I haven't seen anything like this on other forums. I guess the incentive to gain more coins is pushing people in the abnormal behavior. Greed is bad okay?
You can report them. If it's proven that they're just one person talking to himself for signature earning I'm sure the mods will do something about it.
Edit:
Hm. Looks like bitmixer's campaign is restarting under Lauda's management.
They can start by having a look at this thread.
A ton of posters who can be removed straight away.
