i am starting to think Audiogon profits off the spam...

+1 on having a 'trial period' before posts are automatically accepted.
Unfortunately, it puts a lot of strain on the mods, if they have to screen every new members post.
If the admin does manage to eliminate the spam posts, I hope they have some safeguards for a DDos Attack. These spammers are going to retaliate when they can't keep posting.

To Audiogon:
As someone who comes to Audiogon late at night when I work the spam makes your site unreadable. This is a world wide site so imagine the people reading this 12 hours time difference from the USA.

You guys know which accounts are creating the SPAM. Some good ideas were posted above. What about no NEW accounts can post NEW TOPICS late at night (USA time) for a few weeks. The spammers will have more difficulty with that and you can kill the accounts that are misbehaving.

None of the suggestions posted so far need manual intervention. This can be automated. I know I could automate this so can your developers.

As above- Thank You Admin.
the spam was really ugly this morning.
