My friend has been doing DP forum for quite some time now and he wants to sell Anime downloads in Buy, Trade, and Sell forum. The episodes are legal and all and I did some research and saw people selling DBs for them also, but still it seems kind of gray hat. example: someone offers 5gb of anime to be put up on their website to share. Does anyone know if that's against DP's rules? It doesn't really address it.
I think if they are "legal" your friend will be fine. Just keep in mind the $5.00 rule. Things priced less that must be offerred in the freebies section the last time I looked.
