Well, it appears that chess.com does not use recognition as an independent state to decide which flags to include. Scotland and Hong Kong are represented with their flags, while the Republic of Abkhazia, which is recognized by four UN member states, is not.
There are COUNTRIES MISSING

What is a country is recognized by just 1 or 2 members of the UN? Would it count then?
It counts in proportion to the amount of members that recognize it. So .5%.

What about BERNIESANDERSISANIDIOTLAND
Where is that? I want to go there.
Apparently, it's not the U.S. unfortunately :/

Also there is Easter Island as well, all of those stone heads want their freedom !
They should get an Easter Bunny flag.

I hope staff understands I fight for freedom
no. all you do is waste the time of staff and others with your inane topics.
you have freedom, but, you abuse it.
