Dear user,

We are making updates to the eBay Buyer Protection Policy, as well as the eBay Privacy Policy. (...) These updates go into effect for existing customers on June 20.

(...)

* We reserve the right to suspend a buyer's coverage under the eBay Buyer Protection Policy if we suspect that buyer is colluding with a seller to misdeclare the value or type of an item for evading customs fees.

(...)

* When deciding a case, eBay may review item details, messages between the buyer and seller in eBay Messages, seller responses to questions, and other sources of information related to the case.

(...)

* We may use third-party identity services such as Facebook Connect to enable you to sign-on to eBay, and provide tools that will enable you to use data you have collected on other sites to improve your shopping experience on eBay.
