I wanted to make a Twitter / X account but the sign-up flow requires you to solve 10 of those puzzles where you have to rotate the animal with the matching symbol to be oriented in the direction that the hand with that symbol is pointing in. After putting up with this next-gen captcha to train X's algorithm for free, it asked me to do another 10 because supposedly it couldn't tell if I'm a human or not. So I decided not to bother with making an account since it's clearly trying to monetize by obtaining free training data for its ML. I also don't trust that they're not attempting to associate performance on these types of tasks with someone's identity to infer things about them and sell that data further.

Is this what it now takes for a sign-up to be credibly done by a human? Or is it just a cheap attempt to obtain free training sets from people who aren't being paid to label data?
