I used to only use Facebook for events, then they dropped support for iCal. I used to use Facebook for birthdays. See also the iCal droppage.

Facebook is useless to me now, this story gave me the final kick to add Facebook to my pi-hole to begin the rehab process.

Rip the bandaid off, let the healing begin. I’ll find some other way for sorting out events.

Also you can’t do that with a bot. At least not legit via API. They blocked access to events after the Cambridge thing
