Yeah, I see. Though, I think they do realize that they are jerks. They just simply don't care. As you know and have mentioned in the OP, anonymity grants the ability to say anything without repercussion. At least, not for the particular individual. We have a lot of nihilists on this website. Just these solipsistic pieces of shit who think they can say and do anything to anyone, and it'll never matter. I used to be that way, and then I realized that people can actually get really hurt, and I have regrettably done so in the past. It's sad that I had to learn that the hard way, and it just goes to show that people are just inherently bad. Personally, I'd just recommend sticking to private groups from now on. I know you've tried that, but it's really all I can offer as advice.
