friends following stat account?

Has ig changed their Algo? All of a sudden lots of people that follow my personal ig account (my friends) have begin following my larger accounts (still not big enough for me to understand why), that they have no idea I run

I've noticed sometimes is will say, followed by xxx, xxx, xxx so for example if they see your larger accounts, it sometimes saying followed by "your personal" even though you don't follow it on your personal, idk maybe IG tracks accounts used from same device or something. I've been noticing this too, even though i dont follow with my personal, it says followed by "me"

The same for what Thenub says, I noticed that maybe it is the location you are posting from aswell. People who didn't know my niche account, started following aswell. However, last week I accidently invited fb friends with my niche account. Like 10 people asked if my personal was hacked, as my name was now connected with the bigger one xD

Interested about this thread. Hope to read more opinions about the issue.
