Don't forget about catphishing as well. That's when some dude pretends to be a female to try get their victim to let their guard down and send them bitcoins (because obviously a woman would never scam anyone - they're far too nice for that). Seen it happen a fair few times here and there's probably much more that we don't see as people will be too embarrassed to come clean and then also all the attempted times - users like Alia etc: https://bitcointalk.org/index.php?topic=3032057.0
