Buzz: The perfect spam platform?

Buzz is out, genius or a privacy fiasco or just another me-too, depending on your view. Those topics have been covered to death already, but one thing I haven't seen talked about is how easy it makes spamming. And I don't mean shouting inanities to all your friends - that's what it's for, after all - I'm talking about targeted spam by spammers, like the blog spam that used to be a huge problem.

Here is the problem as I see it:

1. You can follow anyone you want simply by adding their email address.
2. When they "buzz", you are notified.
3. When you comment, they see your response.

Does this seem like a bad idea to anyone else? I have a feeling that Google is going to have to allow people to "accept" followers, bringing it that much closer to Facebook.
