Patreon changed its billing from California, USA to Dublin, Ireland for this month. So a lot of banks rejected the transactions as possible fraud.

This would be recoverable ... except that Patreon’s systems seem to have automatically wiped all patronage relationships with a bounced transaction!

there is no news writeup yet, but start at this twitter thread:

IF YOU SPONSOR SOMEONE ON PATREON: go in and check your transactions for August, and re-send them if they bounced. The “retry” link is located in your billing history. (Maybe.)

Patreon are being vague and trying to play it down. We *assume* they are trying to un-bugger their screwup.

Also, payments via Payoneer have been disabled for now, so that hits me personally. how annoying.

(Nobody knows why the move to Dublin. Too many chargebacks in California? Irish tax advantages? Not thinking very hard? WHO KNOWS)

UPDATE: Patreon admitted there was a fuckup! And it's up to you to fix it. Sucks to be you, eh. https://circumstances.run/@davidgerard/110833199221347801

“Hey, if you're a Patreon creator and are confused as to why a bunch of your income vanished, it's because Patreon's system appears to have totally collapsed. They sent me an email saying my credit card blocked the payment as fraudulent, and CANCELLED ALL OF MY CREATOR SUPPORT. 1/”

@davidgerard i don't have a "retry" link, or any listed August charges
@takelgryph argh. did your July 1 payment just get cancelled out of existence?
@davidgerard the August 1, maybe -- it was declined by my bank twice because it got mistaken for fraud even after i confirmed it wasn't the first time
@takelgryph for your comfort and protection, citizen
@takelgryph I think mine all go through Dublin anyway (I'm in the UK) so none of mine seem to have failed. Are you able to re-sponsor them?
@davidgerard nope -- the site acts like i'm not subscribed but doesn't give me the option to do anything related to a subscription
@takelgryph argh. please do keep us all updated.
@davidgerard i have a support ticket open, here's hoping it goes somewhere
@takelgryph "we *really are* experiencing unusually high call volumes at this time,"
