Maybe Write Freely? You get 3 blogs for 6 dollars a month or you can host it yourself since it’s open source.

i dont think there is a good soulution for you.
if its out there, somebody will find it.

you could host your own wordpress instance independent of WordPress.com.

and you could add a robots.txt to tell google to not scan your content, or even completly block the user agents of known search engines.

but blocking search engines is rather counterproductive if you want readers to find your blog.

and even then more nefarious crawlers might ignore the robots.txt and spoof their user agent to find you.

What about https://writefreely.org/

There are reputable hosters like https://text.tchncs.de

I think you should clarify the problem first.

Privacy? You lose your privacy the moment you publish your blog anyway.

Is it visibility? You never expected Google to show your blog in most cases.

AI training? You could self-host and hope companies respect your robot.txt. But what's the actual problem if you released your blog to the public in the first place? Anybody could've copy & pasted your blog also before this AI era.

There are two good options: Host your own blog yourself, or join a blogging platform that isn't corporate. I personally use BearBlog but I've heard good things about Write.as as well. These two have free blogging options and don't sell your data. If you want to host it yourself (which is safer), check out Hugo.

Ultimately, bots scrape the entire internet and there's no guarantee they will honor robots.txt of a particular website (which tells bots what they are and aren't allowed to do). If it's on the internet, people can scrape your content and there isn't much you can do about it. That shouldn't stop you from writing or blogging, just don't post very personal data.
