PSA Fraudster Stole my $5,810 While I was trying to sell my college textbook

I GOT SCAMMED OUT OF $5.81K, trying to sell my textbook from my previous semester. The textbook is so expensive that it's hard to sell nor buy back. A fraudster messaged me first. They somehow got into my account and stole my $5.81 K while trying to sell my old textbook. Everything the fraudster did is a total lie, playing games and wasting time on students. A fraudster has counterfeit the cheque. I hate these scumbags.
