I use Whatsapp only for communication with office colleagues. I had my Instagram linked to my mobile number(2fA). Soon my office colleagues' profiles started showing up on my Instagram follow suggestions. This happened despite the fact that I have not uploaded my contact list to Instagram. I had to block all my colleagues on insta, and then remove my number from Instagram profile.
