Yes, those wikis have been reported to Fandom staff already. They are awaiting deletion. :)

The notification issue is likely due to a thread being deleted off your wall somewhere. If there was a message wall thread on your wall that was deleted (before you read it) then it causes what you are experiencing to happen where you can't get away from the notification.

The only way I know to fix it, is to "mark all as read" but that removes all notifications from your inbox. :(
