They have (or had) a system for reactivation that involved endorsement from another account. IIRC it was QR code based, so one of my friends would scan my reactivation QR code and a few verification texts later I’d have my account back. The last time I was banned, it was after I hearted one of my friend’s posts about his graduation.
I don’t have it on hand, but I remember a study from several years ago that tested a variety of pill and tablet medications for actual shelf life. The big takeaway was that the vast majority of medications degrade extremely slowly unless exposed to moisture, sunlight, or excessive heat, and only a few actually become harmful.
TLDR: it’s safe to take an aspirin from the 1940s, but you might need to take two.
