@bobsal u1553115,
No, I really don't think that's it, bobsal.
Hawkeye has become very active at this site (which does not appear to be "dismal nonstop brawling"--it seems to be a more than decent discussion site).

Frank is there too, but he is much less active than Hawkeye.
I see no evidence, at all, that BillRM is there. Because of his tortured, semi-literate manner of presentation, his posts would be relatively easy to spot--particularly if he was continuing to follow Hawkeye, as he did here.
BillRM's sudden disappearance is more like that of OmsigDavid and spendius--a rather abrupt cessation of posting, by a long time active poster, and without any prior warning that an imminent departure was coming. Except it's also possible that he was suspended because he was behaving somewhat bizarrely, in at least one thread, by repeatedly reposting the exact same post, over and over, because he was pissed it was being thumbed down and ignored. The effect of his childish stunt was intentionally disruptive to the flow of that thread. I have no idea what he might have been doing in other threads as well, but it wouldn't surprise me if he was suspended for something.
I don't miss him, I just wonder what happened to him. I don't think he just suddenly decided to go post elsewhere. He was posting quite actively here until three months ago, and then he very suddenly vanished. Puzzling...
