Delaying RSS Feed

[jayonline]

I have RSS feed syndication enabled for my forum. I was wondering if there was a way to artifically delay the new threads getting onto the RSS feed.

I am looking for this feature to prevent getting spam published on the RSS feed. Our community typically cleans up the spam within few hours of it getting posted, but by then RSS feed and all the indexes who capture our RSS feed are already populated by the spam message. Even after we physically delete the message, the indexes still continue to point to the location where spam was posted.

Let me know if above makes sense, and if there is a solution.

Thank you!
