Doing it just for the lulz.
I'm amused but also a little mad.
although I still can't see why anyone would even consider wiring fiat to Gox right now
I did a SEPA wire recently because I was verified and I wasn't on Bitstamp. Now that I'm verified in BS too, I don't need Gox for anything.

Infinity.00% price change
Is that wall actually being eaten, or did he pull 1k of it?
He's pulling, very frequently. It looks scripted, everytime the buy orders get close is when it just disappears for a second. It reappears when the bids get sold into and the action is lower.
It's probably bitstamp's automatic ordering system. Instead of market order or putting a price, "simple" ordering puts and moves the wall for you to the closest price in the opposite side every few minutes.
