It's up to each server's NN. Also anything that can come off as spammy ie hunt train relinks most would fine it ok to kick someone for that. Also if someone asks about FCs you could send them a tell saying hey I have an FC that might fit you instead of using the NN. I don't know how it is on my server as it can make chat go by very fast, but I do know from another person's post about the NN most felt that things like hunt relinks and FC advertisement were not cool to do. Especially if they were spammy.
