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.
Your accounts are always checking in from the same IP. That’s the simplest method of detection. Add some behavioural traits and it’s scarily accurate.
There’s also other identifiers on the phone. IMEI for example.

All this is why I root phones, use the work profile, etc, to limit what apps can access. If preventing access to this info breaks an app, well, I just don’t use that app.
