I use Fritter to browse on twitter (no login needed), which goes pretty well.

However, when trying to find #nostr npubs on twitter to see if its supposed owner really mentioned it, it almost always gives "nothing found" as response, even though once in the 15 tries I am able to see the search results,

for example when trying to validate the npub of #[0], I could not find any tweet from him about an npub, there were no results. However, at the 8th try and with switching from "feed" to "people", in that short time, fritter gave me results where he did mention his presence on Nostr with the same pubkey that I used as search term.

But when I hit on search again, it displays "no results were found". Anyone else having this problem too?
