[asleep.at.the.oars]

I just started getting emails notifying me of stuff posted on the swap. They say that I am subscribed to a category, but when I log in and look in the swap I don't have any subscriptions, and when I follow the unsubscibe link at the bottom of the email it says the "script call malformed".
So, two questions:
1) WTF?
2) What do I need to do in order to quit getting these emails?
Thanks,
