(1) I'm not "sue".
(2) I looked through zounami's posts and didn't see any that were actually mob-worthy. They all looked like valid opinions that comply with board rules. Can you link to one that you thought deserved votes?

So hypothetically speaking, even if I were "sue", which I'm not, it wouldn't be violating board rules.
