Considering how cliché the unsolicited dick pic is... why do guys still send them? Is there a subset of women it works on? I don't get it... then again there is much to the modern dating world I find baffling.
It's probably not really a thing. I'm sure it happens from time to time but I doubt it's anywhere near as prevalent as it's made out to be.
Now trolls sending googled pics to The Guardian or The Mary Sue bloggers to trigger them I can see happening.
