I discovered that Orkut had helpfully created one for me.
How do you know Orkut crreated it?
I've had accounts created "for me" on all sorts of sites.
Turns out I'm not the only person named James Britt. But I just happen to have a particular gmail account with that name, and there are some number of other people who mistakenly use that email address when signing up for things.
(This is one reason I'm a fan of Web sites sending out E-mail verification notices.)
I have about 5 Richard Johns using my Gmail address. No matter how many times I email their contacts back asking them to update their details, I still get a few emails a day for the wrong person!
I'm currently getting spammed by match.com for one of them.
