Yeah, I've done this before on other sites. It's fun for a while.
It is the same as clique behavior in my book.
Hmm...in a different sort of way. I can see where
it would reinforce such, but hell, some of us can't
just drool over one another, all the time.
I rather suspect that you will see that the clique of
those who didn't mind being pranked fitting more
into this, but really, 'tis more or a way of having our
cake (in terms of pranks), and eating it too (in terms
of not infringing on anyone).
I've only outlined ONE general manner that it could
be used. A bit of ingenuity, and it could end up
with clever variations.
