I know I'm being annoying saying this, but I think this needs to pointed out for those who might want to use it.

INAL, this is not legal advice, but a blog made this way is in all likelihood not GDPR-compliant.
As soon as one opens the website, one's IP address (which is personal data) is sent to (and collected by) relay servers the user doesn't even know about.
So one should be mindful of that.

Still cool project, thanks for sharing it!
