We pay with paxum too, what cam sites do NOT pay with paxum at all?
In fact our affiliates are more asking being paid on paxum than payoneer, at least the bigger ones who does not ask for bank wires.
We even pay on redpass but seems not popular. Webmoney is more popular
However I can tell, most cam girls use payoneer, perhaps when epassporte went boom they switched payoneer and kept there. Only very few cam girls use or ask for paxum. So this may be a reason, but it make not much sense to have less pay options for affiliates... as some even ask paypal or cash in envelopes via pigeon etc.
