How many people have TradeHill hired to advertise their Exchange. If someone stole from me, I'd be upset, but I wouldn't advertise for a competitor. MagicalTux can be reached on IRC. Did you try that?
Full disclosure: As of today I've made 0.01 USD from advertising Trade Hill.
That said, I am quite disturbed by the large number of threads accusing mtgox of "STEALING" when there is some sort of technical glitch and absolutely no evidence of malice on the part of mtgox's operators. People need to be very careful of making this sort of accusation; as it reflects badly on YOU, not mtgox.
