Email notifications for old forum posts

[tomojira]

In the last 2 days, there's been at least 4 waves of emails sent out about old forum posts by thegotoguyy, acting as if they're new. I received a huge wave of them at 11:42 a.m. to 11:44 a.m. EST yesterday, then at 12:09 p.m. to 12:10 p.m., again at 3:06 p.m. to 3:07 p.m., and now today at 10:13 a.m. to 10:14 a.m.

A few examples of the old posts that sent notifications:

thegotoguyy had recently requested account deletion, so there could be some connection to that.
