If sitting quiet is fine and dandy for you, good for you, you're fortunate. It must be nice to be so comfortable by default.
If I had to sit around here on hubski merely lurking, I would have left. No joke. I'd have assumed that everyone was ok with the guy who gradually escalated to spewing racist anti-woman violent rhetoric that y'all are harboring here, since he's still here, still shared, still circledotted etc. I mean seriously, his cherry-picking even gets praised for 'fighting the fight'.
Instead, by participating, I bothered to stay around long enough that I learned that most people don't actually want him here. So I stayed.
I mean, if you want people to self select away because of the sleeper trolls, then by all means, aim for the sleeper trolls.
You'll never know what you're missing out on.
