The owners of `queer.af` thought that AF only meant “as f*ck”, without realizing that AF also happens to the be the ISO 3166 code for a country controlled by the Taliban, who didn’t like their domain name [1].
Brits that had `.eu` domains lost their domains due to Brexit [2] (unless they had some other EEA ties).
And if the Chagos deal goes ahead [3] and the British Indian Ocean Territory ceases to exist, then all `.io` domains might disappear too (although considering that `.su`/Soviet Union domains are still a thing, they probably would have stayed around).
