Thankfully we have blocks here.

I just ignore them and move on

I pretend they're dead

I don't make friends, to save having to unmake them.

I have an entire group blocked

I think it is rare to find behaviour as rude in real life as it can get online. Though, in real life a statement such as 'that is a really rude thing to say' usually stops them. I've recently had to tell someone that their behaviour was manipulative and that they should stop.

you cut them out of your life completely.

Don't answer the doorbell, reply to e-mails, online or phone messages or answer the phone...much easier with caller ID and in real life they'll get tired of making a trip to your home and you not answering the door.

I hex them.

In RL I distant myself from them. If they start with extreme rhetoric, I will say something/ confront them to their face. Online if I'm not blocked first, I do the same thing confront them in PM.

avoid them like a plague

I just go the other direction.

I have no difficulty in cutting people out of my life that are bad for me, it is easy, block cell phone #s,block f book, block on email, just tell them to leave you alone.

I tend to push them infront of buses

Stop being a pussy and tell them you don't like them.
