We actually suspect that this might be related to people not getting their email subscriptions for threads that they are subscribed to... so if we can figure out what this is we might be able to fix both issues at once.

These are not technically "Spam" per-se but a automatic email notifying you about other sites that have linked to threads here. But the system is not supposed to send out these emails to our members.

So I promise we are indeed trying to figure out what is going on and will post in this thread with any updates.
