With the impending release of Mastodon 4.2.0, I wanted to highlight the new Public Profile page.
There are several new options here, and they WILL control whether your posts are part of the new full text search. This feature is OPT IN, so if you're wanting your posts to be included, you're going to have to manually give it the thumbs up. If you don't, well, keep on doing what you're doing.
