This might be clearly obvious to 99.999% of you out there, but there are some of you who don't get it. If you do not want your personal information found in Google, then don't post that information on the Internet. I cannot tell you how many times I see people complaining in the various forums, as well in the comments here, that they do not want Google to list such information about them in the search results.
The issue is, they go ahead and list out their social security numbers, ID numbers and other sensitive information in the post itself. Case in point, a Google Web Search Help thread has one such person listing his identity card number in the forums, asking Google to remove that number from their search results. Guess what, now that ID number is not just listed on a geocities domain, but now on a google domain. Yea, good going!
Anyway, if you are in a jam and need content removed from Google, follow the instructions here and hopefully you will be okay. But do not, I repeat, do not, list what you want removed in a public forum.
