How do people get scammed online?

I keep reading how people get scammed on sites like Ebay. For example, they buy an iPhone, pay with Paypal, but then they realize that they were scammed because the iPhone never got sent…
Pretty easy scam as you can see.

But… The victim now has the name and Email of the Paypal account that the money got sent to, so isn't that enough information for the police to find out where that money went to and perhaps even arrest the suspect?

So how do so many people get scammed? Where does their money go to? Someone must be the owner of those Paypal account, so why can't they locate that person?

A lot of these scammers are in other countries where no law can get to them. Not all, but most. I have provided a few links to explain this in detail. There's a lot more to it than just PayPal

How do people get scammed on the net? I hate to say it but it's the truth. Their own stupidity. Most people don't seem to realize how dangerous the internet really is. They seem to think they can get on the net with the sorriest antivirus they can find, Click on everything they see and not get infected.

They seem to think they can get on the net and order off of any site they can find and not lose any money. Or worse, Their identity. Most never do any kind of research at all before ordering from some online company. Most never try to learn how to keep themselves protected while on the net. They don't seem to want to learn how to keep their computers safe by keeping it updated and use the best AV there money can buy. They believe lies and bullshyt that some stranger on the internet tells them.

It's their own stupidity.
