However, if Rivero IS posting under a different name, I haven't seem it. His style is unique enough that it should be apparrant if he was posting with any frequency.
And, while I don't agree with many of Jim's views (particularly the ambiguity over what is NOT allowed to be posted), I do respect him enough to say "Hey, maybe you didn't notice, but the presence of this thread on FR reflects badly on you."
That said, he still chose to leave it here. That's his choice, and he has his reasons which he isn't sharing. Maybe it being a discourse on the "censorship" at FR without all the J_R ass-kissing is enough reason ... or ... \shrug/ ... whatever. Now, if people like me would quit posting to it, the thread would probably just die. :-)
Not necessarily. As of a a few minutes/hours ago, there are 76,170 registered screen names at FR. Even if you sat here 24 hours around the clock, how easy would it be to follow that many screen names? Of course, if you wanted to get technical, there are probably only a couple of hundred people per day to keep up with, but still... My point is that it's easier than you think for a person of adequate intelligence to change their writing style to adapt to changing circumstances.
Although please notice I said "adequate intelligence." I tried it myself once but didn't make it very far before answering a "To: Nita Nuprez" reply under my new name. As I said, it does take at least minimum amount of mental coordination and concentration. ;-)
And yes, if someone is disruptive, it doesn't take Jim very long at all to spot the "new name," especially if he's looking for it.
