Ccbill is always pretty good for me but does scrub a little extra hard. Most of the signups that ccbill rejects for my site (maybe 90%) go through a backup processor and go through clean and never have a problem.
My only problem with ccbill is that they accept a lot of questionable billing practices (having an asterisk instead of explaining that it is recurring, etc.).
Those sites I would assume have a higher chargeback rate forcing ccbill to scrub a bit more on the rest of us - in other words them allowing that is costing me money.
