I realise that this isn’t a bug or a technical issue about the game, and is not even a bug or a technical issue about the forum, but…!
The “are you a human?” question for my account activation was “What US coin is smaller than a quarter but larger than a dime?” I’m not from the USA, and I actually had no idea. I actually had to google US Currency and look at some pictures to work out what the answer is. I guess that really is testing whether it’s a bot trying to sign-up, but it’s a really US-centric question.
Maybe there are a list of questions, and I just got unlucky, but if not, perhaps the forum mods could look at other questions?
I’m thoroughly aware that this is an incredibly petty thing to be complaining about, and it only took two minutes of searching to determine the answer.
