I once saw a total slurp alias start that I make 250 dollars an hour bragging. I asked treffey point blank if he and slurp ever posted from the same computer warning him that the information was potentially available from the RB server logs. He answered that the computer in his office was not secured or monitored at times and he had no control over who used it then.
Whatever that's worth, it should indicate that they know each other. Those posts are in the lost post archives of rb though.
My opinion is they woul dtrade aliases just to maximize confusion and would sometimes forget under the influence of whatever.
I have no doubt whatsoever that All*n was responsible for many of the "Slurp" posts. And I think he was the one who was much more into the personal stuff. All the felching stuff, the obsession with Chris Hall...
I have always wondered if Slurp was Treffy. On Treffy's bad days, they sounded very much the same.
