I always tread the line between OOC and IC pretty closely in trash talk. I just make sure to do it in a way that makes sense IC. Kind of like how WWE has made more of an effort recently to appeal to smark fans with promos. My thinking is that I'm writing for other writers who obviously would understand any sort of double-sided statement and it's respectable to be clever with it. I guess it's just a matter of tact.

I find it far less abrasive than blatantly using insider terms like "heel/face", "jobber", etc. in promos. I think most of the time when people use those terms, they're just being lazy.

As far as real life characters, I don't really have a problem with them and agree with Shane's statement above. I don't think I'd ever run that type of character, it just seems like a pointless way to restrict your own writing to me and I prefer to have total creative control in my writing. In the end, though, this is a fantasy roleplaying game and people should be able to do whatever they want as long as it doesn't directly ruin other people's fun (i.e., using them without permission).
