I think the key to why 99bb, HGMO, and many DreamCash (
) sites convert and retain so well is because from what I've seen Japan and Korea aren?t saturated with free porn. Almost every site jp-sex trades with are pay sites. Plus not to mention that by law their porn must be optically censored and those pay sites offer censor free content.
The only downside is all those Korean and Japanese broadband users use Internet Ninja like crazy! It?s a bitch dealing with so many leaching fucks.
