Currently getting 15k/unique/month (it has dropped a bit less, but steadily getting up after the rewrite and bigfixes).
When the website doesn't have sponsors, I promote my other free macOS tool (https://dockey.publicspace.co) (with a donation option) that get quite a nice flow of visitors from it.
I'd call this a success, although it's not enough to pay the bills or anything :)
I'm using Chrome, with only uBlock Origin Lite but disabling it ~shows no change~ appears to allow it to work.
Looking at the requests with uBOL disabled, app.68194690.js and 5.5caaec0f.js both returned 404, everything else returned 200/202.
and with uBOL enabled https://plausible.hey.si/js/script.hash.outbound-links.js shows as blocked. maybe that's the issue?
