Contests/Giveaways

The other day I was going through my Google Feed and spotted a very interesting post at Merry With Children.

I found the article on Social Media, Promotions and the law really interesting.  After reading it, I definitely look at all the contests/giveaways very differently.

I think I am just going to stay away from hosting them and will think twice about entering them.

What are your thoughts on the links above, and/or contests in general?
