They stated an email linked to him was connected to suspicious transactions, Zhou Tong himself acknowledges this. IMO, Zhou Tong has to be more worried that he publicly acknowledged previous association with a black market operator and is claiming they have hacked him. On top of that he is acting as an intermediary between this 'alleged' culprit and the affected parties in relaying his offer of a partial payback in exchange for not pursuing criminal investigations.
Would have been nice to keep me in the loop at that point, then.
Zhou's explanation sounds convincing, but as previously said it is not up to us to judge, and legal action is most likely unavoidable at this point.
Either way, I believe many here would appreciate to know who they can turn themselves to to get things moving forward.
If you go to a judge after publicly humiliating Zhou Tong, I am pretty sure the judge will throw the case out. If you had wanted to go to law enforcement in the first place, you should have done that prior to posting any public statement in the first place.
