Facebook: Reminding Several Thousand Spamtraps to Join

Yesterday and today Facebook emailed several thousand of my spamtraps, reminding them that “just one step” was needed to join the social networking site. The problem is, none of these spamtraps ever *asked* to join Facebook. None of them send email. Some of them never existed at all, and of those that were once live email addresses, several were closed in the late 1990s — before Facebook existed. Facebook sent these emails from their own IPs; no ESP was involved.

Spamcop is already listing most of the emitting IPs for these spams. I have no idea whether Facebook is the target of a massive forge subscriptions attack or somebody thought that it would be a good idea to spam a purchased or email appended list over Christmas week. This is ridiculous, however. Facebook needs to fix whatever allowed it to happen, soonest.
