Try using Twitter's search box for "nostr", or any nearly any popular npub address. You will likely see an error message saying "Something went wrong, but don't fret --- it's not your fault."
Also clicks on the hashtag #MarchOffTwitter will result in the same error message.

Don't fret, it's not your fault. It's centralized censorship's fault.
but who in 2023 still use twatter? It's pointless.
I tested this just now, and a nostr search works just fine.
You must not be restricted yet. Had a friend try it just now from a totally different computer and they saw the same "Don't fret, it's not your fault" error message.
