Couldn spammers just sue or DoS the blacklist?
To protect against DoS attacks, the blacklist might have to be distributed through a p2p network. I don’t think lawsuits would be much of a threat, though. A blacklist of spamvertised sites could legitimately claim that it wasn’t intended specifically for use by FFBs. There’s a genuine need for such blacklists to aid in spam filtering. To evade filters, spammers now change their domain names regularly. When a filter sees a domain name for the first time, it would be very helpful if there were a list it could check to see if other users had reported spams containing it. If FFBs happened to use this list too, well, that would be be done without the knowledge of the administrators, just as those naughty “affiliates” are spamming without the knowledge of the sites they send traffic too.
