My guess is that it's a sock puppet of someone already on the site who has a bone to pick. Seems too personal to just be a pop in.
I actually deliberately don't mention this place on subs like /redditalternatives. I don't want more of them here LOL. That said, I'm not sure we're famous for our friendly discourse? I would be skeptical of that claim anyway. Everyone seems to agree we're rough around the edges and maybe just as rough as we were 5 years ago. A comment which I've considered and I am willing to accept. I remember many times telling people who made posts about how they didn't like hubski, that they should just leave. And that was when I thought it was in its heyday. That said I also kind of suspected this guy might be an alt. But who knows. My sister speculated that our home state was "hiding something" from us because she didn't see new COVID data posted for the past 4 days. Turns out she was looking in the wrong place. I think most conspiracy theories go like that.
