Is about.pinterest.com Safe?

Wouldn't let me report content violating the policy: "Contains any information or content that’s illegal (Show explanation)" I spotted some Illegal use of the word free. Per: hxxp://www.ftc.gov/bcp/guides/free.htm. I right click, choose "report this pin" ... "this goes against our policies" ... and then REQUIRES I choose between "Nudity or pornography," "Hurtful content," and "gore". I pick the second, and then am FORCED to choose, if I want to continue to report, between Harassing me or my child Harassing a friend Harassing a public figure Hate speech towards a group of people and Self harm. None of which are remotely appropriate. WTF, pinterest?
