As a reminder, purchasing in-game items from unauthorized sellers is a violation of the Ingress Terms of Service. This week, we’ve taken action against various Item Sellers and have banned over 6,000 accounts related to these stores. We will continue to remove items from Agent inventories that originate from third-party sellers. This means that any items purchased through third-party websites or services will disappear from inventories - even if these items were passed to other players unknowingly.

In addition, we will now be temporarily or permanently banning Agents that are found to have repeatedly purchased items after receiving warnings previously. We appreciate your cooperation in promoting fair gameplay and we will continue to make a best effort to ensure that the actions of those who play fairly are protected.

Edit clarification: We'll only ban accounts that directly purchased the items.
