i don't run PTC site :S i have seen PTC script integrated with AlertPay.. which script are you using?
PP do not banned any ptc site without a reason. And if u'r running an aurora site with the very2 low cashout, PP will be the best option. Most ptc banned got lots of dispute by their members. But, this doesn't mean u can used their service easily. They have strict rules regarding ptc so better before use their service u write to them 1st and ask what u should do. If you choose to use AP, from AP menu click on Business Tools. Then click on link under Standard Integration or Advanced Integration. After enter ur site url u'll given code that u need to insert s'where in ur site. Anything else just follow the instructions.
