Where exactly did he admit to being the scammer impersonating you on Telegram? I didn't get that
OgNasty said that he would be contacting the police on who he thinks did it. He also said that he thinks owlcatz is the person who he thinks did it. Logically owlcatz then assumed that, because of this, Og would be contacting the police on him.
According to Og, this means that owlcatz is guilty.
