Why do you need to have a face? You certainly don't use smartphones (or any device with a camera or microphone) with your alternate personas. I occasionally want a photo, but I just find something fun online.

And about style. Mirimir only writes in English. I draw on my experience working with Americans, including many from the South. My meatspace identity never uses English online.

I just tagged myself in a bunch of stock photos (with the same few models) to foil the algorithms. Haven't tested the effects since I've long disabled facial-recognition tagging in my profile, though.

I suppose someday they might implement features to try to detect and filter out that kind of thing, but then it will time to abandon the platform totally.

There's no need for a data hoarder to rely on platform specific facial recognition - they'll presumably ingest all photos and tag/group them themselves. This of course includes images where you've been photographed in a group/public place. I imagine it's pretty trivial to "walk" from a single known-good photo (eg: booking / surveillance photo taken in connection to a "suspicious" public gathering, atm cctv, or where a person is figuring in the same photo as a known "person of interest") - to ~99.9% of all photos in the dataset...
