When was Lisk caught?

Excuse me, but I'm a bit confused about the timeline. Could you please clarify when exactly was Lisk, the cryptocurrency project, "caught"? Do you mean when was there a notable incident or controversy surrounding Lisk that garnered public attention? Or perhaps you're referring to a specific instance when Lisk's development or operations were impacted in some way? Could you elaborate on the context so I can provide a more accurate response?
