I've decided to stop paying for infrastructure with anything that has a name attached, which in practice means Monero and nothing else. Not BTC with a mixer, not "crypto accepted" meaning they run it through a processor that KYCs me at the door.
What I've found so far is that a lot of providers list XMR on a payments page and then the checkout either errors, quotes an expired rate, or hands you off to something that wants an email confirmation with a receipt attached.
So: who takes it, who takes it properly, and who has quietly dropped it in the last year? Post what you paid and roughly when. I'll take reports over opinions.
