THANK YOU FOR POSTING THIS. I have consistently resisted ever following, or even looking at the profiles of obvious IG thots and yet recently, because my IG account only follows a handful of others and runs out of content quickly, IG has been FILLING my feed with IG models. Not just one, not just a few, like a healthy amount of scrolling is required to get beyond them to other types of sponsored content.
I cannot for the life of me figure it out. I'm sure something I did or revealed has tagged me as "likely to find this content captivating" but I don't and I wish I could flag it as such. My best guess is that because I follow some "BRO" accounts (qualified captain, i70 things, etc) and happen to fall in gender/age pairing where that kind of content is a reliable draw, they'll keep trying.
I mostly maintain my account to follow hobbies and local businesses, but I'm about to shitcan it for the second or third time.
