Google collects absolutely everything possible and tries to connect the dots. They have everything posted publicly in their archives along with everything you've ever given them in private, and anything others have given them. If you've ever used Android with Google services, they have had access to everything about you. For Google, nothing is mundane; nothing goes under their radar.
If you did it with someone else’s photo and THEY said it was doxxing, I think I’d be inclined to side with them. Since it’s your own photo I reckon you get to decide whether or not it’s doxxing.
I’d hesitate to do it myself, but I send a lot of lemmy posts to my friends, who are very intentionally not all equally apprised of my interests/identity lmao
If even doing the traditional equivalent was as bad as the basis of this question implies it may be, then one could say I may have kinda taken themisstep.
