I've run out of ideas. Training spamassassin would probably work, but
I'm not sure if it wouldn't cause disturbs in the mail server.
Did we drop the double opt-in idea?
- User submits a note (with valid email address)
- We send mail with a token URL
- User clicks URL
- Note is approved and posted
Max 5 notes per address per day. Or x notes per domain/IP per day..
Yes, the evil side COULD be automated, but it's a lot more difficult
than a simple post.

Well but who's gonna implement that? :) When will the "to-be-approved" list be cleaned? etc..
