In spain we are over 400 that have informed about this to police, and we had information about the owner of scrypt before. I must insist that everyone of you that has lost money on scrypt informs to the authorities of your countries, so they get to investigate it and get the data they have about "Marcelo" in other countries.
People, come on, do it, inform to authorities, you cant just be lazy and let others take your money.
If you have information about the guy enough to find him why would you waste time with the police? Just persuade him to cough up funds. 400 people should be able to hire an expert in persuading debtors.
Perhaps informing the press would be better. 400 reports to the police, well... they maybe cannot do much. But I am sure that 400 reports to a journal will put them to inform public in general.
At least people would be more wary of scams.
