> How do you protect yourself ?

As a "end-user" one of the most effective way is to either disable js, which isn't the most practical thing for most of us. You can also use ublock-origin, it doesn't only block ads! You can also throw a lying-DNS in the chain, either by using something like Quad9 or a local resolver with appropriate blocklists (think of unbound or for a more user-friendly solution piehole)

Also an anti-virus can help detect the usual stealer that will be dropped by these FakeCaptcha/ClickFix attack, but they are also easily bypassed, that's why you need multiple layers of protection : each of them can and will fail
