It's usual that WordPress stores comment author name and email in the user's browser cookies, so next time the visitor has to comment, they have their name and email already filled in automatically.
My question is:
Is it possible for WordPress to store a visitor's comment cookies on two computers at different locations, but probably using the same ISP?
I'm asking this because I've seen someone else's name and email address stored in the comment form of a WordPress powered blog I was reading. My computer is password protected and nobody used it except me. And this happened not once, not twice but many times (every time a random unknown name and email). Even I've seen a "Your comment is waiting moderation" message.
And since I believed every browser maintains it's cookies for its own, this behavior is strange to me.
