Captcha.

It does all Anubis does. If a scrapper wants to solve it automatically it's computer intensive, they have to run AI inference, but for the user it's just a little time consuming.

With captchas you don't run aggressive software unauthorized on anyone's computer.

Solution did exist. But Anubis is "trendy" and they are masters in PR within some specific circles of people who always wants the lastest most trendiest thing.

But good old captcha would achieve the same result as Anubis, in a more sustainable way.

Or at least give user an option of running or not running the challenge and leave the page. And make clear for the user that their hardware is going to run an intensive task. It really feels very aggressive to have a webpage to run basically a cryptominer unauthorized in your computer. And for me having a cargirl as a mascot does not forgive the rudeness of it.
