I'd like to see a watchword feature that works in the opposite way of the current one. I.e. it will not accept a new address if it *does* contains the watchword.
This way, when I am inundated with spam from a spammer creating addresses by adding different characters to a known spamgourmet address, I can block him without affecting my ability to create other addresses.
This happened to me the other day. I would prefer to just use a term from the address he is using to create new spamgourmet addresses to block him, instead of being forced to use the current watchword method which constrains how I make future addresses.
