Since when does a non us exchange performs criminal record searches on its users ?
They are or at least were a Santa Monica California based exchange that was more recently taken over by ANX BTC out of Hong Kong.
I am quite sure the ANX takeover occurred quite a while after the incident with Agent Force.
Also I remember reading that the background checks were illegal, therefore they were NOT supposed to be doing them, because in most cases you need to get informed consent from whomever you plan to do a criminal background check legally, something that Agent Force would have no trouble doing without consent given his position with the DEA.
