The only "service" that I know of that does this is the passage of time, and you probably won't live long enough to see time complete the job for you. I had my only conviction expunged recently, and because it is over twenty years old it doesn't come up in most databases anymore, but it still does in a few, for whatever reason. Given enough time, things do disappear, but you have no control over it. The inernet age has made expungement much less effective than it was originally intended to be. It is simply too easy to find information, for those who are determined to find out and know where to look. Lawyers will cotinue to sell expungement because they know it will sell, to those looking to "erase" the past. They know it doesn't erase the past, but they will let you believe what you want to believe and take your money, and try to be as "honest" with you as they feel they have to be. Everybody who get an expungement has to face at some point the reality of what it does, and cannot, accomplish, and that is not an easy time. The world as a whole will never forgive you for whatever you did, all you can do is take solace in the fact that some measure of forgiveness was extended by an expungement.
