It's likely fake news or a scam claim. In 2011, Bitcoin was worth pennies (around $0.50), and early "faucets" like Gavin Andresen's did give out 5 BTC free to promote adoption—but only for limited valid emails, not endless claims from a single website. Most stories about "free 5 BTC" are exaggerated retroactively, as millions would exceed the supply. No verified 2011 site gave unlimited free BTC; check blockchain history or sites like bitcoinfaucet.org for real examples.
