We may need to retain personal information if there are valid grounds under data protection laws for us to do so (for example, for the defense of legal claims or freedom of expression) but we will let you know if that is the case. Where you have requested that we erase personal information that has been made available publicly on the Service and there are grounds for erasure, we will use reasonable steps to try to tell others that are displaying the personal information or providing links to the personal information to erase it too.
