Someone somehow hacked into my account and keeps posting stupid shit. My apologies.

Can you give your account back to the hacker because his posts are better than yours?

How about you go get ur girl for me. She gives way better head than ever. Go fuck yourself you trolling asshole.

That's not very original, or mature.

Who's We, where's Here, who's They and who does Us entail?

We probably means other convicts.
Here is likely jail.
They is probably society.
