Can someone sue me for harassing their Vampire Role-Play account on twitter because I'm just starting a little trouble
Depends on what you mean by 'harrass'. If you threaten violence ir sexually harrass people you will be violating laws that could get you into big trouble. And most likely if Twitter gets enough complaints they can block your account.
I don't think so. :)
No. (But who has time to harass people for fun on Twitter..?)
Yes, my mom has sued my dad for insulting her on fb. They court ruled it as harassment and she won.
