A "Great Handmade Gifts for Men" pitch is fine; it is very very different from acting as a personal go-between for one specific seller and a magazine.
Eta: If someone convos me from a blog requesting a free item, or from a magazine requesting a free item, I sometimes report them as a spammer - we get a lot of those, generally from places that are just trying to get free stuff (or free things to giveaway to increase their blog traffic, which is the same thing as free stuff). I've been featured a few legitimate places and not once has anyone asked for free product.
It seems like it would be a lot more efficient for Admin to just un-block the magazines they consider legitimate from the spammer list when they get marked that way by sellers. Otherwise, it seems like it's the seller's choice whether to respond to a request from a magazine or a blog or whatever, and I don't see why admin would feel the need to get involved?
