Hey guys,
Restraining order is impossible and a bad idea. I-F is a platform for people to come and voice their opinions so everyone should be able to participate in discussions. If two people cant stand each other then I suggest the respective DT of the section to have a talk with concerned members and make them stay away from each other's threads if they don't have anything good to provide there.
Mods doesn't have to close down the entire thread, they can move the posts that violates the rules so others can peacefully continue their discussions.
I guess certain members from particular forums where they are labelled as troublemakers with a lot of warnings, they can be banned for a limited time from that forum. If they come back or makes MID, mods can just give them WL raiseJ
PS! This is something the bolly DT need to consider and decide as they know the members and situation better than anyone else:)
