I don't know. Didn't receive an email or anything and only really used Instagram to bookmark recipes and view food pics of a friend's restaurant. Noticed last night that I was getting a black screen with a "something went wrong" message. Deleted cookies earlier, tried to login and it's telling me that the account doesn't exist.

I did disable (not delete) Facebook at the beginning of the year. Maybe they delete accounts after a while across their network of data mining sites? Anyway, with this nostr is now officially my only social media "site". Works for me.
