To be fair, the term "paywall" is kind of misleading here; just by looking at it, it's hardly obvious that it also refers to things like "sign up" (or "disable your adblocker", etc). It's unfortunate that less opaque terms like "signupwall" are too awkward to supplant it. (Of course, if they did, we'd probably have the opposite problem, of people pretending something's not a signupwall because you can pay without signing up. If socialdemocrat has any suggestions for a term for this single concept that's etymologically compatible with both of those special cases, I'd quite like to hear them.)
