Flavor Flav appeared as a guest judge on Dancing with the Stars and sparked attention because he chose scores that were unexpectedly lower for Alix Earle and Val Chmerkovskiy during the Rock & Roll Hall of Fame Night. He later explained that a scoring mishap occurred: he says he meant to give a 10 but accidentally entered a 9 on the computer, and the crew couldn’t change it after the fact. This led to some backlash because, with a corrected score, the couple could have achieved a perfect 40 out of 40 that night.
If you’d like, I can summarize the public reactions and the official statements from Flav and the show, or pull the latest updates and context from multiple outlets.
