I never sent it in, instead emailing and asking if there was any other way to get verified, but never got a reply, and a short while later they deleted my account and all of the pictures and data with it. I'm pretty bummed out because in losing all that, I lost most of my pictures from high school. I have almost no pictures of myself or my friends for roughly a 7 year span of time.
It's my fault 100% for not backing it up, but that's not the point. I was more frustrated with the fact that, for no apparent reason, my entire account was locked and they demanded pretty intense verification to even just get it back. I haven't used Facebook or any of its platforms since, but I have to say it felt pretty gross to be handled like that.
It's pretty sus that these companies use our data for everything but have no actual express responsibility to it.
