Also iirc posts to Ani.Social communities get bridged to #Bluesky through Web Bridgy similar to how the same posts federate to #Mastodon, meaning title and a link to the OP.

Yet to test in that regard, but if the bridge picks comments to those posts as a whole and parses potential hashtags as functional tags, and Mastodon does the same, you could maybe add a comment to your posts with relevant tags too (though again, maybe better to avoid spamming).
