Not sure you can see them (at all the moment but . . ) if you have the person on your ignore list.
It's only a neg though. It won't hurt with all that rep you'll get.
I don't think it will. If you spam or annoy everyone you'll get negged. If you don't the chances are you won't.And to add to that, Bozza can see what's being written if he recieves a complaint so that should deter bullying. And it can be switched off.
It's OK.
