I don't know that it definitely does. What I do think is that any strong socio-political opinions which are nurtured largely in online spaces tend to feature people who behave in this kind of way if the platform permits.
The only reason I think people on here don't explicitly wish harm/death on those they disagree with in some parts of this site is because they'll be banned.
I think some just think "fuck it", make a sock account like the one above who called Alcove the C word, and say what they want to say.
