I'm a 29yo Irishman with a Google Account. Who put me on Orkut? As a 19yo lady from American Samoa?

My most recent login, it said, was 29 December 2007. I have no recollection of ever creating or logging in to an Orkut account. I <i>presume</i> that no-one has got hold of my Google Account password and used it to maliciously register me to Orkut. And no, I wasn't drunk over Christmastime.
