Human-friendly hosted blog platform?

"Why aren’t you more serious?" [1] brought back memories of writing a blog on a free-as-in-beer hosted platform and then stopping because I realized readers without ad blockers were being served ads.

To me, human-friendly means:

- Absolutely no ads shown to any user, ever, for any reason. A blog is a blog is a blog, not an advertising platform.

- Sysadmining, including things like DDOS protection, package updates, making sure there's enough disk space, etc. is handled completely by the host company, not me. I'd love to have the time to self-host, but I don't.

- Comments work out of the box, which means a spam filter and manual moderation are a must.

- Web feed of articles.

- Basic anonymous metrics like reads per article per day.

- Easy backup/export of articles, media and comments to a portable format.
