that's a totally different issue, you asked as if you were just thinking of putting a link from your profile to your blog.....plus myspace redirects the links anyway so no link juice is passed.
I agree, it's just a link, I don't think so it against Google ToS anne ahira health tutur anne ahira burnthefat burnthefat-blog anne ahira with nubar nurananiarcos nurana
Putting a link on your personal profile is not spam and not against the Google TOS. But spamming with links in comments of other users profiles is. As already said, you will not get visits by any Google crawlers because all links redirect to a MySpace warning page before leaving the site. And not only this, but there are many possibilities that a user may report you to MySpace team for spamming. So I suggest better not to risk it.
