Most likley what is known as a "sleeper account" -- an extra account set up long ago for contingency purposes -- so that when the poster gets his regular FReeper account banned for bad behavior, he has an old established account, with a few old posts to make it look real, which he can then start using again, thus not drawing the same scrutiny a new account would immediately following a banning.
The only people who would know to do this would be someone who has been banned multiple times over the years, or a professional troll.
If the "sleeper troll" comment has been directed at me, I can assure everyone here that it is false. However, I suspect that the author of the claim is well aware of the methods for circumventing banishment, as he has used these tactics repeatedly on my own site and many others.
My account name is the same one that I have used on many sites. I have never employed mor needed to employ a sock puppet.
It appears that this site is as bad as many of the Liberal sites when it comes to ad hominem attack replacing intelligent rebuttal. For shame.
