Although they differ from Twitter Likes, note that Mastodon Favorites are not private. For an example, I’ll refer to one of your toots:
https://mastodon.social/@justhach/110696151311920356
Viewing it in the Mastodon web interface, I see an indication that 2 people marked it as a Favorite. I can then click to see those 2 usernames, listed here:
https://mastodon.social/@justhach/110696151311920356/favourites
Such listings are limited though. For example, I’m viewing a toot that you boosted, and I see an indication that it has been marked as a Favorite by 816 users; but when I click to view their names, I see only 40 of them listed.
Although to me it is interesting that, even without literal copying, a generator might be capable of potentially emulating some key features of a specified source. Can this sometimes arguably extend beyond just “an aesthetic”? We’ve all seen examples similar to this one (from the SD online demo, default setting, with a familiar public-domain source) — https://i.imgur.com/PUJs3RL.png
