Tofu seems to be leading, but I voted for the last three on the list as they are furthest from the one you don't want found. The user name I use here is different from the girl name I use IRL for the simple reason I don't want anyone finding me. You may want to do a search on "Personally Identifiable Information" and studiously avoid including any of it. First off would be your real name or any other name you use IRL. Then you need to avoid reference to where you live, your birthdate, and names of close family members, and the list goes on...
Ismabob is random enough to serve all of these ends, so I add my +++ for this one.
