All I need to know are the names of the characters that I've blacklisted and that I'm sent [message from blacklisted user] instead of the actual content of a message from a blacklisted user.

When you go to a store and buy something, do they take your money, put it in the cash register and hand you back your change, or do they hand you the cash register and let you do what you want with it? Same thing. You're effectively claiming that there's no way to handle the transaction without the customer having access to the money in the cash register.
Incorrect. Your thinking is in the clouds rather than of results. It would be extremely easy for a stalker to use player search to discover an alt of someone blocking them by comparing the list against a control account. Doesn't matter if blacklist is handled client side or server side. There is no way around it.
