Photo by Chris Unger/Zuffa LLC Reinier de Ridder knew beating a former UFC champion like Robert Whittaker would get him a lot of attention and plenty of callouts from fighters who suddenly wanted to challenge him. Perhaps chief among them is one-time title challenger Paulo Costa , who stopped a two-fight skid with a decision win over Roman Kopylov at UFC 318 , and he immediately started launching insults at de Ridder following his win over Whittaker. Even days later, Costa was still going on his tirade on social media but it turns out many of his responses were directed at a fake account that didn’t actually belong to de Ridder.
