i mean unless they can dox you they are not a real world threat. at most they will report you and try to get you banned, which is annoying, but not going to really impact you in a large way.

in real life, yes, troll type people will try to ruin your social reputation. i had women in college spread claims of sexual assault when i rejected them for sex. they got their comeuppance eventually but it sucked to be harassed by random people who believed their lies. and a lot of people are increasingly mentally unwell and unhinged and will resort to violence if you upset them.
