Knowing how much data is private isn't a useful quantity? If it were per-user I would agree. Honestly, even knowing "a private video was posted at such and such time" for a website like Twitter isn't a big deal (and this is good, because Twitter also uses an auto-increment key for all of their posts, or at least used to until not that long ago if somehow they recently stopped).
(FWIW, Facebook actually used auto-increment keys for a long long time for their users. I don't remember when they stopped, but before they did they went through a long period of manual ID range allocation.)
- zaarn 6y agoTwitter uses Snowflakes, simialr to FB and other services. They scale better than manual ID range allocation and don't entirely behave like auto-increment. The big part is that it can contain gaps. So there is no way to tell if an ID doesn't exist because you lack access or because it was skipped over.
