Take it from the recent article Erasing the Digital Past by Nick Bolton: "ONCE something is online, it can be very difficult, if not impossible, to delete. So tweaking one’s online reputation usually boils down to gaming the search engines. Image-conscious people with an understanding of the Web’s architecture can try doing it themselves, by populating the Web with favorable content. That might involve setting up their own Web site or blog, or signing up for popular social networks like Facebook, Twitter and LinkedIn."
Mahmoud, you need to do some serious tweaking. Consider the wonders social media engagement has done for @RealRobMugabe - now, no one even thinks about him any more.
But since you may be facing some self-imposed firewalls that limit your access to these tools and allow you to erase unflattering results through obfuscation, you may want to use the phone and call up an online reputation manager.
