If you so want to prove that you are a Person, not bots, to counter the Sybil attack, which no one is using and from which no coin has yet been harmed, how do you like this idea?
Remove these flips completely.
They are not needed.
We are really all different people with different cultures, different logic, different sense of humor, etc.
And actually it all reminds Google captcha and it annoys everyone and is outdated.
Take an example from Binance. The most modern and multi-functional trading platform.
But do they use Google captcha to protect against bots? No.
They use a Slide Captcha with puzzle.

Devs can leave the opportunity for users to create these puzzles themselves through the tools built into the wallet.
They can be done by the developers themselves. Or you can connect geetest website.
As you wish.
But the main thing, now in validations, there will be no misunderstanding what this flip means. And no numbering needs.
All people assemble puzzles the same way, regardless of cultural or any other differences.
And thats all, no problem.
3-5 puzzles is enough.
This might work out. Different cultures takes it to different understanding and different creation, there are so many differences between how we see stuffs arround us.
And as you said earlier, no censorship, stop sending the idea to any newbie coming that he needs to take invite only from dev bc his identity will be killed. Or how they did after this epoch, cutted 200 verified members out of their rights to invite. But ofc older shillers here, they won't care. They care only to shill everything the dev is saying
