Comment Tried Mastodon, failed at #GuessTheHashtag (Score 1) 70
A Twitter-branded Mastodon instance
It'd have to support full-text search by default. Mastodon, last I checked, was still in practice stuck with tags-only search that fails unless both the poster and searcher manage to correctly #GuessTheHashtag. I've read that Mastodon added in version 4.2.0, but I've never got it to work because it's not the default: the posting user has to deliberately seek out how to opt into full-text search before sending posts, and the administrator of the searcher's instance has to spend a lot more money for a much larger VPS with the RAM for Elasticsearch or OpenSearch.
