ImageTwist Question. Do they pay for referral affiliates?

Does ImageTwist pay for referral affiliates? It doesn't seem so to me.

I've referred to them lots of referrals. They name the referrals "points" which does't give any explaintion anywhere of what "points" means

There doesn't seem to be a way to cash out the refferal points. I contacted last month and no response.

I do know they pay out for viewing images but i'm talking about the referrals.

Is there any other ImageTwist websites that we can make money?
