i received that message every time i tried to get on GT from Chile (except once when i was using an unknown wifi signal). it stopped happening in Argentina. i never did anything except click on GT link from my favourites menu or from google. i couldn't even get on when trying to reply to pm notifications in my email.
this was the message:
Angel was indeed very special. Unfortunately I think my pictures from your visit went MIA on my old self destructive hard drive, but I still remember how sweet she was and how much she and Phene liked each other.
