It seems to be impossible to turn of email notifications from Cryptsy. Every time a user makes a wallet to wallet transaction, cryptsy sends an email containing ALL the data - how much of which currency was sent from user's cyptsy wallet to external wallet. This effectively links an email address to cryptsy account and to the outgoing wallet.
We all know that big brother loves to collect emails. Cryptsy helps them to easily compile a database of millions of wallet addresses - link them to emails - link emails to people, thus uncovering who owns what and does business with whom.
Cryptsy why don't you:
A - give people the ability to disable email notifications if they want
B - send a little less info in the notification email - if you must
users:
A if your going to dodge taxes and paranoid of governments, dont use cryptsy
B if you think th government waste time on you, rather then big threats, you need your ego checked
C even if government have all email data, your not that important for them to stalk you, so get on with your life
