YouseTube , FarceBook, & the rest

I just "report" them and block them. Sometimes, the site administrators
delete them.

I remember watching a video, that people were saying was funny. I commented that I didn't think it was funny. I got messages from people who were calling me an "inbred hick" and "a$$h0!e", and they were telling me to "f*** my w**** mother." Just because I said I didn't think the video was funny. I never signed in again. These kinds of comments, plus the racist comments that Josepp has mentioned probably wouldn't be said by these people if they were talking to you in person.
