It's now completely borked. Whatever caches were in place with those instances are now outdated and they can't access Twitter data.

And setting up burner accounts to get around this won't work in the long term either as Elon's whole point of buying Twitter was to get rid of bots and these burner accounts. Being a burner account is now a violation of ToS and they will demand a verified phone number or just close your account.

I would also be very skeptical of the term "temporary".
