So what are we supposed to do now?

@Romaticize block. 

Containing these people would be even harder here.

@Romaticize you want only people who share your thought to be in a social networking side......that's never going to happen. on every type of public platform you will find people from different ideology and schools you can only have a debate WITH THEM. THAT'S IT
@Romaticize if they abuse they are going to get banned. That's all. Atleast we can be sure of that now.
@Romaticize We don't have to do anything. Not until they do something. If there is abuse, as of course there will be, you just have to report once, and that should be enough.
