Not that I really care, since it was a joke thread, but its an annoyance that someone rates the thread low without even posting.
Obviously you do or you would not bring up

I give you the same advice I give my daughter when my son is trying to pester or get on her nerves --- ignore and he will stop! If you keep bringing the subject and drawing attention to the fact -- then you are doing exactly what that person wants you to do! Of course, this is assuming you are correct and that some people are trying "poop on other peoples threads." If people care enough to vote, the system will take care of itself. If it really is that big of a deal to you (which you say it is not BUT then you mention it), PM people and tell them to take a stand.
