Sex offender mixup on MySpace and AmeriTrade Spam

Last week there were some interesting identity developments.
summary: Ms. Jessica Davis had her Myspace profile eliminated because it matched a name in a sex offender database. She tried to resolve it with Myspace but they were very unhelpful. She went to the press after learning about a new information sharing agreement between MySpace and states attorney generals. She is planning to go into law and public service and did not want to be in a position for the rest of her life defending her innocence because they put her in some database.
AmeriTrade Spam: “On April 14, 2007, I signed up for an AmeriTrade account using an e-mail address consisting of 16 random alphanumeric characters, which I never gave to anyone else. On May 15, I started receiving pump-and-dump stock spams sent to that e-mail address. I was hardly the first person to discover that this happens. Almost all of the top hits in a Google search for “ameritrade spam” are from people with the same story: they used a unique address for each service that they sign up with, so they could tell if any company ever leaked their address to a spammer, and the address they gave to AmeriTrade started getting stock spam. “
