Well... this is very strange.
I run a forum - 2 years old.
As soon as my users are registered with phpbb3-forum, they get a set of free wedding-tools, which only is viewable by the owner herself of that account.
One of the tools is a "wishlist" for their wedding. Since you have to own the account to look at you own wishlist - it's not possible for google to index those pages - but google has actually done that, and here is how:
I know for sure - that this tdimmen-user is a real person. I know this because in my db, the user have filled out information that a googlebot couldn't have done by itself.
But the tdimmen-user is logged in all the time now - as in: Never logs out, always active, reading forums and stuff, and if I check the user, I get this information from the phpb33 software:
tdimmen IP: 22.214.171.124 » Whois
Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)
Anyone knows how this is possible?
To me, it really looks like googlebot has adopted the tdimmen-useraccount - but that's very wierd, it has to know tdimmen-password to be able to log in!?
