alt Hacker NewsNotably, this started happening the day that I made my TikTok account public. My Instagram feed began to be a copy of my TikTok feed. The exact same videos. Even after changing my Tiktok back to private and deleting all of my followers, the feeds are still identical, every single day. My behavior is not. On Instagram, I follow and interact with very different accounts than on TikTok. It seems to me that Instagram is buying or accessing TikTok's data, and it is not through advertising providers, because the identical content is coming directly from Instagram/TikTok and not promoted ads.
There are three possibilities though. One is Instagram copying TikTok, without their knowledge, the other is Instagram copying your TikTok feed with their knowledge but not their blessing, and finally Instagram copying your TikTok feed with TikTok's knowledge and their blessing. If we take a look at http://TikTok.com/robots.txt, it seems if you make your TikTok public, TikTok is happy to let Instagram take a look at it (but not a number of AI crawlers). What Instagram does with it is up to them, but it's in robots.txt.
