I think we can change payment processor. I use paypal, but I also have Neteller and Payza although I prefer Neteller.
I joined Clixsense because it was a PTC page, I am a premium user, although I do not have any referrals. The offers I almost can not apply, the tasks sometimes take away too much time and not pay much, although times when they are simple and quick things, like seeing images I make them. Surveys are always willing to do them, but most times they reject me, other than they send me very few. So the only certainty is to entertain me 5 or 8 minutes a day looking at ads.
I think that instead of removing options to make money, there is a need to try to increase them.
