Okay, just got back....
It's my computer in my home. DSL connection. Web site is not mine, info is being pulled off of it regarding my posts and searches from that site and shows up on Google. There is one spam post which is not good, listed on Google that has nothing to do with me. Plus the other stuff doesn't need to be out there. Nothing incriminating but just don't want it there.
I think I know what you're talking about, but you can't really fix that since the website isn't yours. You could tell the person who owns the site to put the robots.txt in the root of the website. Otherwise, the google posts and stuff could be either because he has no verification code for registering users (if the Google person is a user) and if it isn't, and it's just an ad, then you can't stop that because the ad could be what's helping pay for the website.
So it's beyond you, either way.
