It's on the same level as putting content on the page in a 1pt white-on-white font. Sure, the content is technically there, but humans can't read it.

Expert sex change at least has the content on the page, unadulterated, after you scroll past a bunch of ad blocks. Totally different from what Quora does.

I haven't been directed to expert sex change in sometime, perhaps because of Stack Overflow, but unless they've changed, expert sex change is deceptive, they don't say "real answers below ads", they provide answers that make it look as though you need to register, then the provide a crap ton of ads then the real answers. I'd say they are somewhat different from Quora, but not necessarily any less deceptive. I'd say they are gaming Google.

Yea - at least the answers are on the page. Quora is 100% filtered cannot view. They should be banned from the index.

EE used to hide the actual answers until you signed up, but it hurt their SEO. (I think there was a temporary scandal where they showed the Googlebot different pages but it got fixed.)
