It seems like Amber only follows certain types of people too. Plenty of blue ticked real celebrities but not many random ordinary people. I think this gives the Butchiee9 theory some weight along with it being made private, lack of posts, covering up of previous image/identity, lack of internet presence.
Anyone know of any really good reverse image search engines? Experimental AI driven ones or something, as I managed to grab the original profile picture but obviously the Normie-Net level engines brought up fuck all. It would help if Instagram was indexed properly by search engines as I'm willing to bet this image is stolen from a random Insta account somewhere.
