Spam-buster rewired by spammers to become spam-buster-buster
I just deleted a spam comment where the spammy words (the name of a drug and links to sites where you can buy it) had some of the characters encoded as entities, to foil simple keyword-based spam filters.
It’s funny because this exact technique has been used as a counter-measure to spam for quite some time to “safely” publish email addresses, on the theory that an automated email address harvester won’t be smart enough to resolve the entities.
