I think it's impossible to get on cryptsy only by vote. You know that, you must "donate"
BTC to it. I think it's not necessary.
You could say the same for mintpal, where most coins seem to buy votes. We are getting good numbers of genuine mintpal votes from our community, not from buying them. We could do the same to get on cryptsy.
Any exchange will list any coin if they smell big money. It's all about greed. There isn't even one reputable alt. coin exchange which don't operate out of pure greed. Poloniex at least add interesting coins, unlike many other exchanges. Cryptsy is most disgusting and shady of them all, but it's also the biggest one with highest volume.
