Donation problem.

Tried donating today and I get an error saying "Payment has been blocked for you." It talks about fraud and asks me to attach my bank statement(s). I find it fishy. I donated earlier and it was successful and now this? Anyone else have this problem? Thanks.

Repeated payments with the same credit card is a sure way to get a fraud alert triggered.
Paysafewall seems to be very sensible to that kind of suspicious behavior, so you will have to give information to prove you're the actual card owner.
