I use it for about 5 years, to publish javascript file (proxy auto-configuration) and serve the contents over different gateways.
It is a huge server traffic saver.
Used to use it to host different static websites on custom domains while Cloudflare's gateway was working, stopped using it for this purpose since its sunset in 2024.
Neocities used to publish their websites over IPFS, this feature got broken (for years) and finally got removed: https://github.com/neocities/neocities/issues/352
