I notice a lot of affiliates pay out via paxum but paxum doesn’t accept personal accounts from the US (as they told me through email) Did you make a business account to accept paxum, if so how hard is it to get the “supporting” documents? If not do you just skip those affiliates?
I am not sure about which sponsors you are talking about, but the ones I use offer other payment methods such as a bank wire and a check, so you are not limited to only using Paxum. I have a personal account there and I am based in the Europe but I am not a big fan of it so I can not tell you that.
They are very slow to send credit cards and even to respond to support tickets (I had problems with transferring my money and I resolved it after two weeks, so you have to be very patient) but unfortunately they are still the only adult alternative to PayPal. I only use them if the program isn’t paying through other methods.
