Hmm; interesting. Well, I did run across an early one; a user by the name of OReich. He pretended he was doing meet-ups with people in Florida for Paullapalooza. See
this page and others in his profile to see his very first posts about this. It turns out he was totally bogus and made up his intentions to do meet-ups.
He ended up shilling for Israel. His group was similar (or same?) to this group that Israel was paying to defend it online. In fact, the
USA Today article was called Israel to pay students to defend it online.
The funny thing is that there was guy named MaybeMaybeNot who was doing the exact same thing as OReich. MaybeMaybeNot would rant and rave about Israel. He would rant and rave about RPFers being "anti-semites." He would scream, "You ppl!" I confronted OReich about it, and he acknowledged MaybeMaybeNot was his sock.
