Poster child - Tradução em português

This summer Alex became the poster child of the banished underage Google user. The day he realized he'd been locked out of Gmail, his father wrote a blog entry titled "Google made my son cry," and then posted it on his Twitter account, and it went viral. Martin's decadeold blog typically gets 100 visits per day; on July 4, he had 40,000 hits.

Then again, perhaps the biggest irony behind Alex's poster-boy status is that once enough kids hear his story, they'll learn they need to lie about their ages on Google+.
