They've removed the blurred-text overlay and now are returning pseudo-blurred-text images, so afaict there's no way to get the remaining answers without logging in. I can't seem to find actual confirmation of it, but a lot of people were skeptical of whether Quora's previous approach (returning text but rendering it non-user-readable) was consistent with Google's rules against search-engine cloaking, so maybe they changed it to avoid angering Google.
