A few days ago, a foreign account that seems to be an independent online store followed me on instagram. Seeing as though I might be willing to check out some of the items for sale on the acc, I decided to follow it back. Then next thing you know, the account has been sending me some explicit photos of his genitals in my private messages. I decided to block him but then, my friend also says that she’s been a victim of the account herself. I want to report the account myself but how can I do it? Any advice would do. Thanks.
