Welp, I picked a hell of a night to go to bed early...
There seems to be some pearl-clutching over whether this is amounting to "stalking." I don't think it is.
A few members have Brac's contact info, only because Brac gave it to them at some point. No one has doxxed him. Those members who had his contacts reached out to him directly, discreetly and with good intentions. Brac may not have received it, or maybe he did and is ignoring it. Either way, someone who cares about his well-being has tried, and after no response, has left it alone. If I had a friend IRL who hasn't been heard from in a while, I would try to contact them to make sure everything is OK. If I didn't hear back, then I'd leave them be.
As far as "sleuthing," death notices and other online newspaper stuff is obviously public info. Real estate transactions are deemed public information. AFAIK, no one is digging into his personal background, looking for criminal records, using paid search sites, etc. Everyone has been discreet re Brac's contact info.
True, this is an online community and we really don't know much about the guy beyond what he has chosen to share. We can only speculate as to what is really going on, and many of us, myself included, have done some speculation. But Brac is a friend to us, nonetheless. If Brac wants to rejoin us, he will do so of his own volition. If not, then he's moved on to other things.
Nobody here is doing anything that would rise to the level of "stalking."
