Back in October of 2012 I devised a way of blocking abuse of my mailing list server by detecting mailbait abusers (mailbait.info offers a ‘service’ to fill your, or someone else, mailbox with unwanted mailing list subscriptions). In June of 2013 I refined the technique.

Basically I detected if someone was visiting the mailing list subscribe page from mailbait.info and sent them to a special page that also annoyed them by popping up hundreds of javascript alerts about not spamming people.

Regardless of the popups, people still try to use mailbait to involuntarily subscribe people to my lists (well, try at least, my lists require a closed loop confirmation system).

Today I received the following threat from a mailbait.info user ..

I’m inclined to ignore the ‘warning’ … but I find it somewhat satisfying that my approach has annoyed someone sufficiently.

As an added measure, I’ve updated my system security mechanism to block any IP that attempts to use the mailbait service more than once.
