While searching for my own name I found out someone in the same town with the same name was sentenced to 50 years in prison. The guy was nailed for possession of about 3 kilo's of cocaine. The intent to distribute was pretty obvious. Let's just say none of my old friends or girlfriends have ever contacted me since.
Which brings up a nifty scenario if you don't want to be contacted by old girlfriends. Just find a state vs drug dealer affidavit online somewhere, fill in the blanks with you name, create your own legal sounding domain name, and post it. Private reg on the dns is a good idea. This happened to me coincidentally but I was thinking it would work exactly the same if I did it to myself on purpose. It's not illegal to make a hoax directed towards yourself right? It works surprisingly well.
1. Old hats will not take the trouble to wade through the justice system to find your contact info.
2. They probably wouldn't want to after reading your affidavit anyway.
Make social engineering statements in the affidavit to deter old hat resurrection. For female deterrent add things like "hit girlfriend and mother in the face with large bludgeoning tool (baseball bat)". For male deterrent add things like "stabbed neighbor in the testicles with a hunting knife".
