Anyone can leave comments on tf-Media sites.

But the catch is, comments are not displayed on the site until they are moderated. They are held in an approval queue until the owner of the site or a super user approves them. Once they are approved they appear on the site.

Comments are also scanned by our spam modules. This looks for any tell-tale signs of spam. This is a great feature and will save you time by eliminating the obvious spam comments. So, in the end, the only comments you need to approve are real comments typed by a human.
