The Realm of Cereal and Goats

The major search engines and Google in particular will respect a no search flag. But it would need to be in the webpage base directory.. meaning that it could only be done by TI staff.

Why don't you post in the TI suggestions forum that just the profiles and blogs be excluded from Google crawls? TI won't want to exclude the entire site, as Google pulls in a lot of new members. But almost all of the content is in the forums. So excluding just profiles and blogs would do much to bolster member privacy, while having an negligible effect on Google traffic into this site.

Seems like a great solution. The mechanism for doing this is the robots exclusion protocol, but it's usually just referred to as "robots.txt". It's a list that specifies which site directories are to be excluded i.e. profiles and blogs.

There should be nothing in your profile you do not want to share in any case. If someone wanted to see your profile I'm sure they would go further than a Google anyway.

Don't use your T-I username for anything else.

Problem solved.
