So, long story short. I needed to create new facebook account (well my first plan was to order Instagram ads but for some absurd reason I need to have IG business account for that and to have business account I need to link my fb profile with IG account and as soon as I linked my fb profile all my friends got notification “your friend blahblah is now in instagram as blahblah2” and well..it’s so stupid and actually out of topic).
Edit: actual point:
Anyway to avoid all this, I created new fb account, I was using chrome, I was in incognito and for signing up I used mobile number that I have never used before for signing up, like nowhere. Now what’s interesting – after signing up facebook suggests friends and those friend suggestions are like extremely good – my actual profile was no.2 suggestion and all suggestions are my close friends. I used for name absolutely random words, it doesn’t have connection with my actual profile. Amazing. How do they do that?
