Simple. I don’t use it. I used to selfhost my own Nitter instance but after the changes breaking it, I simply stopped using it for updates on accounts. Sure it sucks, but it’s something I’m just accepting. The official nitter.net instance still works, but the fixes being tested and worked on are not totally reliable just yet. There’s no guarantee it will ever work as well as it did in the past. Usually, privacy advocates and activists and such who are actually worth listening to will have a mastodon or other fediverse account that people can follow. I follow those instead.
