I definitely had a .co.nr domain before a .tk. I think I also remember (I was likely 13, so its been a while) that they had an "English" test question on the sign up form that read something like "A Britney Spears is a:" and one of the options was "Hamburger".

Looking back this could have been to slow robots down, but I distinctly remember one if the terms being you speak and host English content.

Another service I used a lot was " dominosfree" which had a bunch of .gs domains that looked like CC-tlds. I used .ca.gs a lot.

Ah, co.cc, the tld that was full of php reverse shells!

.co.nr was strange because it put your page inside of an iframe and required advertisement of the service.

Yeah, the cloaking was annoying - navigation across pages wouldn’t update the URL.

I think I had co.nr too! I just dont remember if it was like .tk or if it was one of those webhosts.
