Search engines like Pipl allow you to find information on just about anyone. If you’d like to get your information removed, Computerworld has a giant list of opt-out links for the most popular sites.
Each service has different rules for opting out, and they don’t make it easy to find the instructions. Removing your information may take some work, but you’ll be safer in the long run. If you do opt-out, run a search a month or so later and see if they honored your request.
