I did the following:
- I found out where it was hosted and send them an email explaining them why and how that shop is a scam
- I found out where they hosted the domain and wrote the registrar an abuse email
- I wrote an email to the banks where the bank accounts where active
The scammer had a webchat module active and he/she did wrote back to me, nothing came out through that, nonetheless:
next day, both webshops were gone due to being taken offline from the hosters.
I do believe, that they do have a chance because literaly no one cares. I have seen mentioning of one of those two shops older then 6 month. I pissed at them with very little effort in a very short time.
I do hope i helped out.
