My suggestion is to use some privacy focused browser for instagram, like other commenters said. If you don’t want to move fully to another browser, then at least use that browser only for insta. I would still expect them to be able to track you, since they likely have a big team working on the tracking tools. It’s their entire product after all… I am not on instagram so I don’t know if it works, but another thing you can do is to make it a game to click the least interesting things you see on your feed. Go in the post, spend a bit of time there, if you are feeling like putting effort drop a like or comment too. Pick the lowest effort posts, things you would never do or buy, but I would avoid politics (you don’t want to start seeing biasing content that might actually succeed in changing your opinion). All modern platforms will start showing more and more of that extremely uninteresting content and make the feed less addictive to you and I think also your friends. Don’t click or linger too much on an interesting thing on your feed, just duckduckgo it from the other browser instead. The interests data is the most valuable thing they have on you, and they know all your friends so they know who you are even if you used pseudonyms. It’s hard at the beginning, but it gets easier as the suggestions get worse. You don’t have to spend much time on that too.
