I appreciate why you're doing this, but the whole set up makes me really uneasy :/
It's almost as if you're creating an anonymous bullying squad and it doesn't sit right with me.
Often I've found that patience and peace work better than hatred, and then if nothing happens, report, report, report or else just block and give them no attention as it is nearly always for attention.
I know the feeling of wanting to completely hate someone, but this isn't the right way to go about it. It's a cowards tool. If you want to hate, do it under your own name and be brave enough to face the consequences? idk it just seems so wrong to me
