what’s the point of this scam?

so i received a message on instagram on my private account, with less that 30 followers. the message read “hii :) my friend was stalking ur profile all day, idk where she got it but she def likes u” and sent me another users profile.

the account that dm’d me had 0 followers and 0 following, and the account they sent me had about 1000 but was private. there’s also several copies of the same account. super weird!
