i seem to have misunderstood. my reading was that they were tracking when selfies were being deleted from the user’s device itself (and not off the facebook platform).

if the article is about selfies being deleted from the user’s posts on meta platforms, otoh, i don’t understand why there’s a privacy brouhaha. surely their tos and privacy policy covers using your data and actions on their platforms for targeted advertising?

there is a conversation that needs to be had there about the morality of such a move, sure, but i don’t see a privacy violation.
