The service can delete specific content without prior notice and without a reason
This service can delete specific content. Usually they will claim they reserve the right to do it at their sole discretion, which is legalese for saying they won't give a specific reason. If the terms say they will not notify you, it shall be included in the quote but if it does not explicitly say they will give you a notice, it can be reasonably inferred that they can do it without telling you.
