This has been obvious to me for years, even without the direct notifications to follow someone particularly. I uploaded a subset of my contacts to IG pre-Facebook acquisition, must have been ~5 years ago, and to this day I get follow suggestions (that I've never clicked on) which one would have no reason to believe are good unless that data was retained (e.g. for contacts who are not "mutually well connected" with other people I follow).
