What about the paypal donation button or a vBulletin subscription donation service?
(search button isn't working for me so I don't know if these have been considered):
PayPal Donation Button

I don't know much about the donation button but I do know that it's probably safer than sending money to a person as a donation method, donators can post how much they donated and Sythe can confirm they have via PayPal and have their perks added.
- Accept donations made with credit cards, debit cards, and PayPal right away.
- No monthly, set-up, or cancellation fees. Only low transaction fees.
- Donors don't need a PayPal account to make their donations.
vBulletin subscription donation service
This is another way that could be used for donating. vBulletin should have this feature as paid subscriptions (donators can do one-time donations and keep their perks). I've donated on bobbamarket (trading website for habbo) via the vBulletin subscription service before, and you get the donation features after you've donated.
