It has been publicly discussed and written in articles, shorting groups, and they are VERY powerful, pay individuals to bash stocks. These folks will use all means at their disposal to take down the pps, and their damn good at it.

I don't know how iHang handles this, but at Agoracom, there's an IP check tool link for every single post, so any member can click on it to see it the person has more than one alias.

MOD's there, they are call Hub Leaders on that site, of which I am on many boards, can ban the accounts, or have admin do it.

iHub apparently does not monitor it 100%, but I'll give them credit for banning accounts if they are notified.

It's bad press to allow multiple alais...report it to them if suspect.
