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.
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 ..
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.
