Okay guys, few quick points worth noting here.
First and foremost - THIS IS WHY YOU MUST ALWAYS BUY YOUR EXPENSIVE THINGS ON CREDIT CARD!
Tattoo that statement on your head and poke out your eyeball if you ever don't.
Because it provides 100% protection against this kind of scam. If you buy a £1700 camera from an internet website and pay on debit card after having read this post then your foolishness is beyond measure, or you're a billionare and don't care.
Secondly, the police can do little to stop this. The people are not in the UK, and will be exceptionally difficult to locate with international cooperation.
There is currently no central blacklist for scam websites per-se, so there's not a lot the police can do.
Reiterate the important point: USE A CREDIT CARD!
In case anybody isn't already aware, when you buy on a credit card (NOT a debit card) the card provider has a liability in the event that you don't receive the goods and will refund you the lost money. Do this with a debit card and you will probably be screwed.
