credit card and upgrading

hi,
is there any other methode or planned at least to upgrade an account.
i have the money but i dont have a credit-card.
how about paypal?

Not that I'm aware of...

Not sure if a prepaid debit card would be an option...?

Most "monetary middle-men" like PayPal won't accept payments on behalf of Danbooru because of our pornographic and other questionable content.

You can pay via Stripe with your credit card on the safebooru page: https://safebooru.donmai.us/user_upgrade/new

Edit: I misread the question, sorry.
