I have gone into my privacy settings, and under "Search" there's an option whch says "Public Search Results" and a box marked "Allow" which I have left unticked. I presume this means I will then be excluded from the ordinary search engines like Google - ????

Every blessed time I open that page I get a dialogue box which says

Worried about search engines? Your information is safe.
There have been misleading rumors recently about Facebook indexing all your information on Google. This is not true. Facebook created public search listings in 2007 to enable people to search for your name and see a link to your Facebook profile. They will still only see a basic set of information.

and no matter how many times I click the yes-I-see-this-yes-I-get-it-you-don't-have-to-keep-telling-me button, it reappears the next time and totally covers up my page info until I click it again. This little game is getting old.

This is annoying enough, but even more so is the fact that this notice doesn't really tell you anything. They only see "a basic set of information"? That's still information, as far as I am concerned. It includes things I want available within Facebook but not to the general outside world. And how safe is "safe"? Until someone works out how to hack it? That's just a gold-plated challenge to the black-hat brigade.

Let's hope leaving the "Allow" box unticked means what it says -
