Apropos of nothing in particular, if you're reading this you probably care enough to support your instance and its admins, but maybe you reported a card lost and never went back to fix your donations, or maybe you never got around to supporting your instance after a move. Why not fix that now?
On my instance, the admin is @jerry and when I go to his user page, I see some links:
Patreon: https://www.patreon.com/infosecexchange
Ko-Fi: https://ko-fi.com/infosecexchange
Liberapay: https://liberapay.com/Infosec.exchange/
Chances are really good that if you go to the user page for the admin on your instance, you'll see similar links. You know what to do!
