and it warrants a ban, well... that's your call as a moderator.
All I can tell you is that it's not my handle, and that my posts are – and always have been – original. In fact it's not uncommon for the entire board to disagree with me on something (e.g...
http://www.tigerboard.com/boards/view.php?message=18923106 )
Lastly, this is really making you look petty. If you ban tigrito, he can simply register another handle... and then you'd be in a silly cat-and-mouse game with him. Seems like a pointless waste of time, but as I said... your call.
