have all the "victims" realised that its precisely because you let the scammer get away with it in the past that he/she has continued to scam lotsa folks since then??
get off your butt and nail the bugger! with so much info, it cannot be too difficult to nail him. get all the victims together to make a police report together so that the men in blue knows its machiam a syndicate at work and over an extended period of time.
I had made a police report yesterday already. Nailing that guy down is not easy as due to the grey zone across borders and he knows well about it. For example, the case of the delivery receipt of Air21. Upon receiving this receipt, if you give Air21 a call, the operator will tell you to check the tracking number the next day. If still invalid, they will ask you to check again. This process just continue and they won't tell you that the delivery receipt is real or not. This is the grey zone that the conman used. In addition, the free mail issue like Gmail, yahoo or MSN. The procedure for getting the IP address of the conman is tedious even for the police. This is due to the legal issue involved in privacy policy. So, this is another grey zone. There is so much grey zones in the internet that make it difficult to track this kind of scam. The only way is preventive measures and educating more people about it by providing more information that is easily search-able. Someday, there maybe someone that able to come out with a solution to resolve this type of scamming.
From my case, there's a lot of loopholes that can catch the tail of the conman like collecting money from Western Union (Cebu, Philippines), voice-over-IP call on Friday, phone number, etc. With some efforts (cross-borders, internet expert, etc) made, it is possible to track him down. This is due to he is a conman but is not a professional hacker therefore it is impossible for him to remove all footprint online.
Just my 2cent!
