You never know how your content or your comments, could be interpreted on a Law point of view.
I heard of example as the following:
A person was blogging about her dog and the food she was feeding it.
At one point, her Blog was seen by a company who was selling Dog Food. She was contacted and was asked if she could try some of their food,for free.Of course, she said why not.
Then she kept on blogging about that new Dog food,without really knowing what the Company or the Dog food was all about. She had only been happy to get something for free. Believe it or not,she was charged for false representation, and was fined a lot of money.
The Law considered that,because she accepted the free food, she was like an indirect sale`s person and when the Dog Company was charged for misrepresentation, so was she.
You need to be protected specially if you are jut starting. You don`t want to be shut down before even starting to make money Online.
The rules are more and more severe, and you have enough to worry about. You don`t need to be worried and get involved in a law suit.
So go find out more about that subject and make sure that you protect yourself.
