Just to make it known, html5doctor.com has been completely gutted and overtaken by AI slop.
The domain lapsed in mid-October, and it would appear that some SEO-ghoul is puppeteering the old site to extract what value they can.
I’d suggest it had been registered for the max length of ten years back in 2016, as that lines up with it expiring recently.
Someone is slopping out fake articles attributed to real, known authors and has even gone as far as to edit old content on the site, too.
The site is completely dead and ruined as a historical record.
