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

@dweller ... but in that case, someone simply could insert spam WITHIN an existing thread. That's likely worse than an initial spam thread. I like your initial suggestion ... anyone with less than one week's seniority on the forum must have ANY AND ALL of their proposed posts reviewed by a Moderator.

I have been reporting these as spam, and move on. No big deal. I still get marketing calls on my cell, and I have protections / walls to prevent them. MrD.

+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.
