Either Jack's managed to hack LiveJournal or someone on the staff is spying on us.
A screencap of his profile from a few days ago is
Exhibit A in support of these theories*. That advert cannot possibly have been placed there by accident.
Each scenario is equally likely, although I do think that if Jack had hacked LiveJournal there would be more icons-replaced-by-pornography and the Elvis Costello fangroups would have been deleted (Costello knows what he did). On the other hand, if LiveJournal staff are spying on him, that means I might get to go to Russia and investigate. This has many bonuses: chance to act like the suave secret agent I am, cool furry hats with ear flaps, and the opportunity to send someone a postcard with "From Russia With Love" written on the back. Drawbacks: I understand it's very cold in Russia, and I don't like vodka or Chekhov.
I shall have to ask the boss.
* I do not spend much time looking at Jack's profile longingly. Or sighing in pain at his constant flirtation with anything that looks like it might have erogenous zones. Or sadly contemplating a sparkly Hello Kitty pen I may have confiscated from his desk. I would never do that. Except it's Kuromi and she's my favourite.
