Well according to a DM, I can't actually rip This thread Down.
The reason for this? "it will turn into a forum war"
Seriously, theres a few things to be said about that.
1) If you don't want to start a forum war - Dont allow people to POST things that will start one, especially not things where the only logical action is for the people in question to take them down.
2) If a post is going to have IC reprecussions, possibly resulting in a "forum war" Then these IC reactions should not be stopped by an OOC factor. It would Fuel conflict - Which I seem to recall DM's telling me was an important storytelling Device, and Conflict is what made a concept good.
3) It's completely rediculous this person can do this thing do our characters, and we cannot respond with the most logical action, because of how the other will respond to this conflict (I.E. reposting) To me this just shows sort of a hypocrisy. The DMs want conflict, yet don't allow us to persue it in the most logical IC means, because it will be more work for them.
I mean if someone puts up a note like this about you - What's the first thing you are going to do? leave it there and plot some huge shindig to find out who posted it? I think not. You're going to rip it down. Then plot the shindig.
Basically this is a rant to either have the topic in question Deleted, or to allow me to proceed ICly and rip it down.
I would prefer the latter, as I tend to agree- conflict makes this server so much fun, but to limit our Actions like this is just IMO totally wrong.
