Did you ever notice that there are so many scammers and persons who try sell you something? They have the same approach, same style, phrases etc: pretty girl avatar, "where are you from? I'm Nancy, Kelly from.."
They are so annoying and I thought everybody aware about it. Were you ever approached by scammers?
I also encountered similar situation as you say, on average there are ~ 10 such message daily and will never reply to them, I get really pissed off and every time I ignore or give them blacklist.
