CCBill compliance (as of 2 weeks ago) was really fast. I submitted a site late on Sunday night and I had an approval on Monday afternoon. It took about another week to get Visa approval.

And... the same site, when it went through Paycom the week before got a request from Visa for IDs for some of the models who looked young, but once we provided the IDs to Visa, it was approved the next day. So there's no "age discrimination" except, as Corvett said, that they don't process for models who are underage.
