Maybe it would be enough to somehow get the Services section less 'messy'... Somehow we should clean up the scam topics and get rid of the auto-bump services for some topics (if there's any), in that case all the newbies and all the members could easily find what they're looking for.
(But using the 'search' function could help even more...)
You probably already know the answers to these questions; Scams aren't moderated, and bumping if it's against the rules can be reported, and removed. I'm not sure on the forums moderation stance on auto bump services. I imagine they wouldn't act unless the user has been caught in auto bumping, but offering the service probably is a little bit of a grey area, and would depend on the mod dealing with it.
