webmaster guidelines?

Hiding redirects in javascript or other manipulative methods is bad. Users should always be sent where they expect to go.

Using scraped or stolen content is against the Google webmaster guidelines and it is also against the law. Not a good idea.

Misleading or false information in your rich snippet mark up will result in lower rankings.
