So I have 2 Instagram apps on my phone. Instander is my personal account and instathunder is my “lewd” account (mostly cosplay girls and such). They’re on separate apps and use separate emails, however, my main accounts search page is like 90% cosplay/goth/alt girls. I have never looked that up on my personal account but its all that’s being recommended.
Are they reading information from each other? How can I stop this? Also, how do I get my personal accounts feed to be normal again?
If you are using both accounts from the same IP address and/or phone it is trivial for Meta to figure out it is one person using two separate accounts.
This is what the fingerprinting your phone is for. They save interests and info about you attached to the fingerprint of your device and share that with any other service that asks to retrieve it, including another Instagram account on the same device.
Edit: just fyi, I do not mean actual fingerprint unlocking, but just a unique identifier they create depending on your setup.
On Android, apps can read information from each other as long as both apps consent. If these apps are using the same libraries to connect to Instagram then that library may be enabling sharing data between the two apps.
I assume the situation is similar on iOS.
