I have to verify. All of my accounts.

Agreed.

I hear some say they have this and some say they do not... why is this?
Is it random and a test or what?

I do see that F5 refreshes don't trigger a captcha. (So don't log out of the game?) Even when the game blows up and gives me a red 'Restart' button.

I wonder if those who weren't seeing a captcha now do (upon login, once), or if they were commenting about F5's/restarts at that time.

I have also experienced where I had to turn off ad blocking or ublock origins long enough to get the captcha up. Once up (immediately) they can be re-enabled.
