It’s both horrible discovery and a limited number of creators.
But, for discoverability, https://sepiasearch.org/ might help you find things to watch, since it’s the only good multi-server search I’ve seen. (And run by the peertube devs.)
As with all things email, they probably really wanted to make sure that the mails were delivered and thus were using a commercial MTA to ensure that.
I’d wager, even at 20 or 30 or 40k a year, that’s way less than it’d cost to host infra and have at least two if not three engineers available 24/7 to maintain critical infra.
Looking at my mail, over the years I’ve gotten a couple hundred email from them around certificates and expirations (and other things), and if you assume there’s a couple million sites using these certs, I could easily see how you’d end up in a situation where this could scale in cost very very slowly, until it’s suddenly a major drain.
Sounds like a fantastic plan.
The handwringing about if we’re being nice enough to the alt right is directly contributing to why we have so much mess we’re now having to deal with. The approach seems sane to find music that’s very specifically nazi rock, so they’re being extremely limited in response, imo.
Screw em, kick them out of anywhere you find them, and then nail the door they used to get in shut.
