Quicken Loans founder Dan Gilbert was not happy late Sunday night when his teenage daughters asked about a Motor City Muckraker story that showed the billionaire’s real estate team was erecting cameras and a transmitter without permission on buildings that don’t belong to him.

Before signing off, Gilbert offered a few more kind words.

I know.”Ignore them”.Just once in awhile you have to let the lying venom filled wannabes know that they will be held accountable.Goodnight! — Dan Gilbert (@cavsdan) April 27, 2015

We challenged Gilbert to show an error in the story, but he didn’t respond and instead blocked us on Twitter.

Gilbert also directed his ire at Eric Lacy, a former MLive reporter who often covered entertainment in metro Detroit. Gilbert apparently didn’t think it was very manly of Lacy, who was celebrating his birthday, to tweet about Bruce Jenner, a former gold medalist who revealed that he is transgender.

. @EricLacy This coming from a “tough guy” who spends half his weekend tweeting about Bruce Jenner. Keep smirking, Lacy… — Dan Gilbert (@cavsdan) April 27, 2015

Lacy fired back with kindness.

Thank you, Dan Gilbert! Just inspired me to make a donation to Detroit’s Ruth Ellis Center for homeless LGBTQ youth. http://t.co/dLFaIWZ15J — Eric Lacy (@EricLacy) April 27, 2015
