I don't know how hard this would be to implement, but I thought that this idea was worth sharing and discussing.
The ability to silence a nation from posting on the RMB. This would make moderating a region's RMB much easier. Some posts are worth suppressing, but they aren't worth a ban. There needs to be a middle category: silencing a nation.
Just today I had to talk to two people (https://www.nationstates.net/page=rmb/postid=27480239 & https://www.nationstates.net/page=rmb/postid=27481218) regarding their conduct on the RMB. It would be wonderful if nations with the same ability to suppress messages (Appearance I think?) could silence nations from posting rather than ejecting the nation or suppressing every single message.
