if people are harassing you, you should block them and make a drama.
And then get harassed even more by the people you are drama-ing and then even have the sane users stuff on you for making a drama that just adds to the pile of dramas against the same problem causing users that they're so sick of seeing
It really seems like a lose-lose situation
not alot of people called problem users seem to "actively try to ruin other people's day", it doesn't seem.
Actually the majority of them do and have, that's why they're labelled as 'problem users', some of them are less persistent, sure, but there are also those specific ones who would even follow you to other mediums just to harass you
