LOL, I've checked now a period in which I submitted 4325 shares. 284 are missing.

Months ago Deepbit was moving shares from round to round, now it's making them disappear.
It's a kind of magic, maybe.

I really don't appreciate this pool, but it's the only big hoppable pool (besides slush, and slush is hoppable for a much shorter time). Tycho is locking hoppers' withdrawals, though. Poor tycho, keep my 0.027BTC. It's my present for you. 

Wouldn't it be for hopping on the prop side, with a 10% PPS fee I couldn't see why Deepbit should exist. Everyone can point his/her miner to a pool of pools: safer and much cheaper.
