I am the Admin that approves all new members and I specifically check for spammers and puppets. Occasionally, one or the other gets through but not for long. We have caught minors (no surprise), pedophiles (I let them in G~ caught him and tossed him) and more than a couple of puppets. The member in question's ISP indicated he was where he said he was from, a quick background check indicated he was who he said he was, a Board member had met him a few years ago and I had significant PM communication him. I don't like someone being accused in public (Puppets have usually been dealt with very quietly) and public forum trials ultimately are embarrassing for everyone. We have a distinct shortage of attorneys but a wealth of opinions.
Puppets or shills should not be tolerated by any forum, particularly since they lead to the kind of drama and thread-derailing we've seen here. I would urge our admin staff to pursue those, via ISP logins or other evidence, and remove the posting privileges of the puppet as well as the one pulling the strings.
If anyone has a personal issue with anyone, I suggest you take it up with the member like adults should. If anyone has any evidence of any Puppet, I strongly encourage you to being it to me. I will be happy to check it out and respond accordingly. I would beg anyone not to make accusations without carefully considering the possible ramifications.
