I think the Instagram algorithms are really pissing many bloggers off.
Tess Daly, the make up artist, has been spitting feathers about it recently. She's someone who has a profound disability, so Instagram is her actual career. She's been complaining that some posts get huge outreach but then some are seen by hardly any of her subscribers. She's been saying that people have to post a minimum of four words underneath a post before Instagram considers it user engagement (or something? Don't understand it all, honestly). And unless you like 7 or her posts it's not considered engagement either? I dunno. So she's been urging people to like old posts and comment with four words.
It's all a bit baffling but I can see how frustrating it would for her to have these arbitrary views that are out of her control. Vero or whatever it is, promises to have none of those algorithms. But they must have some, so I'll believe it when I see it.
