People have been using country TLDs as cute URLs for years, and somehow it almost always ends up as a problem, or it furthers harms against the countries who own the TLDs (.io for example). Sure .tv or .io or .af sound fun, (anyone remember del.icio.us?) but it's just not worth it.
And because of that .tk ccTLD is completely disreputable now. Everyone and their mother had one back in the day, which included all the spammers/phishers and their mothers. Now no one trusts .tk domains. Or at least they shouldn't!
Damn! Using .af for a LGBT+ site is insane! The country could have redirected the domain to their own servers and started learning the personal details of those on the site who I imagine wouldn’t be terribly thrilled having an anti-LGBT+ government learn their personal information (namely information not displayed publicly). Specifically, they could put their own servers in front of the domain so they can decrypt it, then forward the traffic on to the legitimate servers, allowing them to get login information and any other data which the user sends or receives.
