tomsawyer above has the right idea. Other private trackers do the same thing... buy a subscription from their "legit" web hosting/email/cheesey seedbox provider (which you don't even necessarily need to use, but which gets you a subdomain or something if you really want it) and get VIP membership for the same length of time on the torrent site (or, in your case, bonus credits). Works great, the service being sold is legal, and the "bonus" doesn't have to be mentioned, since it's just a free extra you get along with your web hosting subscription, right? Find yourselves a partner who already does something anime-related well and use an incentive program... an anime hub, anime DVD reseller or similar, you get $x for every $y you drive to the site, count $x as a donation on the bonus points program. Or "go legit" with some sort of offering yourselves, sell crappy low-level web space (a great concept because fixed costs are low and most of the fee can be applied to the donation) or resell anime collectibles through drop shipping or something. It'll take some research to find the right thing to do but once you have it, no more worries about payment processor fears, because there is no controversy. Maybe your products are overpriced, but that's up to the buyer, right? Wink, wink.
