This is a scary story! Focusing on the Twitter handle sale part: I have the twitter handle @jetsetter, and have been offered multiple thousands of dollars for it (guess who!). Unfortunately, selling a twitter handle is against TOS. Only @israel has been officially allowed to transfer hands for money, that I'm aware of. So trying to broker the sale of a twitter account can allow the buyer to report your 'behavior' to…
Twitter: "I'm sorry, you can't do that."
Israel: "What are you, some kind of Anti-semite!?!"
Twitter: "OK, OK, go ahead and do what you want. See, we're not anti-semite :)"
