Hard to know if Xenu related or X-factor loves the hype related.I think a fair number of the interviews I've seen are "behind the scenes at the X-factor, so I would think the producers let the press in for them.
I'm surprised at the seemingly unrestricted access to twitter, but given they are using twitter for voting the tight control on the official twitter of AI probably isn't in effect.
My guess is as long as the twitter numbers are high they don't really care what goes on, just helps with the hype machine and if the peeps want to make fools of themselves, so much the better as that probably gets more attention than peeps being sane, mature, and appreciative.
My guess is X-factor doesn't care what is being said as long as something is being said.
