For all the help auto complete is, I'd be quite happy to lose it entirely. On the other hand, auto complete should be different on each user's machine because the users past searches influence the results shown. Also, other users may want to see the results this user complains of. In a world with so many people having the same name, trying to control your name bumps up against the rights of everyone else that has the same name. People have to accept that auto complete is not an information source in itself. To suggest it is result's in silliness like this.
