I’ve fixed it so that new people signing up have to be approved by me before they can post. I’ve already deleted 10 or so applications – I’m seeing patterns in the email addresses of the spammers – so if I get a funky application, I just delete it.
There are still likely some that got through before I changed the system – with over 900 people signed up I can’t screen them all, so if you see spam, please just email me and I’ll get rid of it, and the "member" posting it.
