I'm not too into "real identity"[0], but since I tend to manually filter by handles which have passed my personal[1] Turing Test ("has this handle presented ideas and defended them via logic and evidence?"), I would daydream about a checkbox like "no bots, non-heart-transplanted dogs[2], or low-engagement humans".
[0] despite which I've already easily leaked 33+ bits for this handle. Anonymity theatre is much easier than anonymity.
[1] I do seem to fail others' Turing Tests from time to time, so YMMV.
