My first guess is that the downvoter(s) think this is for booking.com...I initially did (but I didn't downvote, because on second look, it isn't clear).

There are a lot of bad stories about working at booking.com...one of those things you don't even know how you know, but you realize it must get brought up a lot for that association (and only that association) to exist with the company.

edit: now I did downvote it for posting a duplicate where a simple list of countries would have sufficed.
