We have spam mail in the Hey! I would suggest you ignore it. I have let Chris know it's there and asked for it to be removed if possible. Just open the ones that are recognisable addresses please.
Spam is an annoying but not threatening problem. I usually manage to remove it within a few hours, so the best way of avoiding it is to subscribe to the daily email update rather than getting an email every time someone posts, so there is a good chance the spam will have been removed by the time you get the update.
I have also been through the list of registered users, banning the obviously machine-generated names. There is a risk that I might have banned legitimate users, so if you suddenly find yourself unable to post please drop me a message and I will reinstate you.
