These security measures follow complaints from parent groups and authorities who were concerned that the site had not gone far enough in providing protection for young people.
The adverts are part of an ongoing campaign by the US Ad Council and the National Centre for Missing & Exploited Children and they aim to educate parents about what measures they can take to protect their children, as well as raising awareness among teenagers on creating safe online relationships.
MySpace.com, began as a site for music fans and has countless bands, musicians and singers on it, both the signed and the unsigned, but it has also become incredibly popular with teens who form friendships there.
Although MySpace forbids minors under 13 from joining, and provides special protection for those aged 14 and 15, children often manage to lie to get around the restrictions.
Earlier this year, two men were arrested in America over sex charges after they allegedly used MySpace.com to meet two girls aged 11 and 14.
But MySpace says it tries to protect minors by flagging up members likely to be under 14 and the company said more than 250,000 flagged profiles have been deleted since it began.
As well as this, teens aged 14 and 15 have restrictions in place on their pages, so that only those on their friends' list can look at their profiles.
