Well, I voted for them to be in The Turf, but I think that the question is probably too vague. For example, if you asked me, "What should happen if someone starts a mock thread in another forum?" I would likely say, "Nothing."
Mock threads will probably crop up everywhere. Mock dispute threads will likely crop up in a dispute forum. Serious threads crop up in Turf. Should we get bent out of shape about that?
If I'm not interested in reading or participating in either one, I simply don't read it.
