Do you allow adult/NSFW images? I think those ones have the most potential of getting traffic, but the quality of the traffic might be less than crypto related images/documents.
Ok i have thought long and hard about this one
People can set there accounts to private and send the download links via emails thru the site or give the links to people , personally there isnt a problem with a picture of a woman or a man (if your a female), but if any hardcore porn set up public will be deleted and any snuff/extreme violence/Pedo garbage , it will be deleted and accounts/IP's/emails will be banned , yes the site is crypto based , and thats the area that it will be promoted , some people may just wish to store or share images and so on , which is kool , but i will monitor as well as a few Moderators as well ..
