How come ebay does not protect the buyer from sellers that rip them off?

Beware of ....he ripped me off and ebay did nothing to support me.

In what way did the seller rip you off?

How come eBay buyers complain without giving the full details of the situation??

[marnotom!]

They probably don't want people pointing out that the eBay support was there but they didn't use it in a timely fashion.
