Ok, so this sort of thing has never happened to me before. I got a random naked arse photo text from an unknown number who I don't know but knew my name!! For context, I'm a pianist and the message read 'there are no bum notes from you wishiwasa'. Bit freaked at them having my name and number when i don't know who they are (can see the back of their head in the photo but doesn't ring any bells). Besides the message was sent in the middle of the day so presumably not a drunken prank....
Wwyd?
