Seems like a lot of spam shows up in the share.ez.no RSS feeds now and then.

My suggestion to fix this:

Add an approval workflow on forum posts, with 2 events:

• an approval by a share.ez.no team member, but not needed for users in a certain group, further called "trusted users group"
• an event that adds the user who submitted the post (the owner), to the "trusted users group"

Once a post of a user was approved, any of his later posts won't require approval. So you have a one-time check requiring human intervention. Good enough I think, as most people at the forums are recurring visitors AFAIK.
