I love to use cbill but when a review of my website was done i was refuse and + i was told to accept visa it will cost me i think $700 If i accept pay-pal i think they will just close my account i know ill be in violations of there terms of use. ima looking for something more like 2checkout for a adult-sites in canada I like the fact that 2checkout gives you a pre pay credit card and you can transfer your founds.
CCbill is the best, however thier fees are really high. You can accept Libery Reserve but thats not used so widely. You can also use Epoch, it allows adult.
