FabeBook has "in memorium" status for accounts of deceased users, I set my dad's FB account to that status when he died 3 years ago. A quick google tells me that Twitter had plans to introduce this kind of feature in 2021, but I don't know if they ever got around to it. They should, and frankly I'm astonished they never put that in before. Facebook did it in 2009.
