have you ever...

blocked someone on here?? I never have, but I'm thinking about blocking this one girl. She never has anything nice to say and all of her comments on people's posts are always always negative and rude. I don't want to block anyone but seeing how awful she acts truly just gives me a headache... Ladies, What should I do? Should I block her? I have reported her several times as well as reporting several of her comments but she's still here.
