The bottom line ought to be, on FR: If it has no newsworthy content, then don't post it.
That goes for any and all Vanity posts as well.
P.S. If you MUST post a Vanity, put it in "Your Opinions/Questions". I've noticed that most stupid, pointless Vanities these days are put in "Miscellaneous." If you point out their faux pas, they'll claim they "didn't know". I don't believe them. I think they just want to make sure they can shove it in front of everyone's face (YO/Q has a "self-limited" audience).
