A call-out was put on the social media platform asking for questions to put to the Blurred Lines singer in what should have been a light-hearted probing.
But using the hashtag #askthicke, many people expressed their outrage at the Canadian chart-topper's lyrics and the video accompanying his big hit which featured naked female models dancing.
Unimpressed online users took the opportunity to ask questions such as "did you really write a rape anthem as a love song for your wife and are you still wondering why she left you?" and, "If one of your songs played in a forest and no one was around to hear it would it still be sexist and gross?".
Another commented: "It might seem like some of the questions on this hashtag are cruel and abusive but Robin, I know you want it."
Last year Thicke was named "sexist of the year" by the campaign group End Violence Against Women Coalition.
