Thanks Mel. I never bothered to check out the link. According to their website it costs $5/month to remove ALL ads. I don't see any other option regarding ads. Perhaps your thinking of the difference between browsing anonymous or logged in? If your anon you get more Ads.
Either CKTG has a grandfathered feature or the feature is no longer active. Seems a rather nominal fee to avoid the issue altogether.
In the meantime, this appears to be the way to report the ads to them:http://help.freeforums.org/support/solu ... e-ad-on-my
It appears that you have to be the owner of the forum to report inappropriate ads?? That seems crazy. But their website is not that clear so maybe i'm misunderstanding and anyone can report (Although you do seem to need to create an account and submit a ticket?? also crazy). They should just have a mailbox to collect this stuff from anyone. If your a forum mod or owner sure open a ticket if you want a response.
