I am getting dozens of spam replies to threads. These are the email reminders that come from the site when someone posts something new. When I click on the link and go to the message thread, the spam comment is typically not there, but the email I get looks completely legit and has the proper links to the actual message thread in it.

Is there anything that can be done to stop these spam emails? I like being notified when someone posts something new, but this is starting to get out of control.
