Happened to me too, and I've downloaded this app only a week ago. One asked me three times, I ended up blocking her because I replied and liked her looks after the first time. I only did it because her looks were beautiful and I wanted to show that.
I don't mind if someone asks for help, especially new players, but please be nice about it.
By the way, if anyone wants to ask me for help, my lookbook ID is 7971721 (Android).
