Other licenses you apply to content you submit may continue after your content is removed. Those licenses may give others, or OpenZeppelin itself, the right to share your content through the forum again. Others who receive content you submit to the forum may violate the terms on which you license your content. You agree that OpenZeppelin will not be liable to you for those violations or their consequences.
