go this site. it makes moderators aware of all the bs that online multiple personalities are being used for...there's even a point in there that talks about a member using multiple nicknames to always take side of the main account. 

All im saying in these forums is that multiple usernames are being used to increase the high reputation of certain member or members. I just want all of you moderators to be aware of those things. Its not an easy task but keep trying.
