I don’t know! In the spirit of the thing I don’t track any of it, though maintenance stuff provides vague insights and an occasional glimpse, and presumably there are server logs that could be pulled. There’s a slow, steady flow of stuff being published. A (seemingly small) proportion is snippets of nonsense, close to empty.
One interesting behavior I noticed. Because txt.fyi is extremely simple http, using no javascript or third party calls, and because nothing is publicized systematically, it is reliable and pseudo-private enough for people to just publish and then use the back button to “edit”, creating a series of published slowly improving drafts.
