Is your code in the format of bsky-social-xxxxx? If so, they've been revoked and replaced with longer codes because people reported that their codes getting brute-forced.
Thanks for replying; I don't know anyone else who has an invite. Yes, mine is in the bsky-social-xxxxx format. I checked my email but I don't see a follow-up invite.
Part of me wonders if this was an intentional 4D chess move on Mastodon’s part to make it look like Elon is silencing competitors and get more attention in the process.
This is increasingly absurd, but I see Twitter has also banned the official ADS-B account and antifascist website It's Going Down (which is mostly polemic op-eds and reports about political demonstrations in the US and Europe, and theoretically well within Twitter's TOS).
I have a bookmark of their mobile web app on my phone’s home screen now. Works great as a replacement if you don’t mind losing features like push notifications and the ability to speak in Spaces! It also has the benefit of tweet drafts syncing from your other web browsers.
