Just my take.
I haven't had any large problems with Cryptsy (yes I knew about their "stealth staking" of customer coins but just factored that into cost of their exchange) other than a few small instances of coins vanishing, however I can not have anything to do with that enterprise until they delist XPY.
I know removing my alt coins isn't going to hurt them but if we all stop using cryptsy until XPY is delisted it would probably make enough of an impression to wake Vern up.
