help on removed extensions by Google

[wecite]

Our extension seem to be removed by Google, the policy/terms pages saying that if we have any doubts we should ask the question here.

Our extension is : jofjnbepnhcbfnpbhchillofcgpeopaj

Our home page is wecite.cn

Please tell us which term/condition/policy we violated so that we can make improvements/changes necessary to get it back online.

Thanks in advance.
