This is legit. Search for 'samy is my hero' with quotes and you'll get reams and reams of myspace accounts, though apparently it has all been cleaned up.

An aquaintance of mine recently managed within 24 hours to become the most popular civilian on myspace with the help of a clever bit of viral javascript imbedded into his myspace page.

By the time myspace shut down their site for a few hours to investigate he had over 1 million requests from unknowing myspace members for him to be listed as their myspace friend. Not only that, but every single one of them had their "my heros" section appended with the phrase "but most of all, samy is my hero". Yes, my aquaintance used his own first name for this.
