I have a very faint recollection of seeing this "watched" under the pic/name status in a thread. If I recall (and It may not be accurate), a mod can use that if their is a potential for someone to be a spammer or something like that. Hey, anyways, you're posting links to your youtube videos, you want people to be encouraged to watch.
Except in that thread, where it was c&p in the thread for illustration, I have never seen it.
I do see text under ataradov's pic that says "Card this guy before serving"
, under mine it just says "Disregard".
