Hi Kim, thank you for your comment. It’s true that encouraging Facebook users to share and tag Facebook posts as part of a contest or giveaway goes against Facebook’s policies. We’ve included examples that do this to illustrate how other brands conduct Facebook contests. It’s up to each user to decide if they wish to follow those practices or use an alternative approach, such as a giveaway app that complies with the policies.

I hope this helps clarify things a little for you.
