Yes of course. Some fake exchangers have been completely sued for this especially if they have been proven to do some money laundering.  I remember bithumb global Korea was rushed by Police last time due to scam token that has been listed on the exchange.

The only thing that bugs me is that about provision or rule on crypto crimes. What if certain country doesnt have that? So how certain guilty can be convicted if he knows that the country his in dont have specifics yet.
