Ah I've been in a similar situation like this before when I stupidly used my well-known username as my name on another SI support site like this. Anyway, long story short, I found that that webpage showed up in a Google search, so I emailed the tech support on that site and what happened was they contacted Google with a request to clear it from the search archives (: And within a day or two it was gone! Doing this may be an alternative in case the reporting thing doesn't work out.
Here are some useful links in how to go about doing that if you wish.

I'm sure yahoo can help with this as well. I wouldn't be surprised if this was a rather common problem d: anyway, I hope you can get it sorted out! I know how much of a worry it is to have your internet info so easily accessed like that
