Both

It's both, actually. It does make it so that I can't post to FB from the same browser I read it in, which is plenty annoying. But also, even when I use a different browser, the majority of the time (by which I mean "every damn time so far, including this one, but maybe I'll get a pass next time...?") I have to play three or four rounds of "make confusing judgement calls about crappy photos" until Google decides it's leeched enough free training for its image-recognition software out of me and no bot would have such a high tolerance for bullshit, which is just aggravating. What is even the point of having this if you have to be logged in to post anyway?
