Techniques are described that allow a user to control and/or restrict dissemination of content by other users related to an account of the user. For example, a request may be received, from a first user account, to restrict presentation of content having a characteristic and received from a second user account. An item of content having the characteristic may be received from the second user account. A first instruction to present a first representation of the item of content is sent to a first computing device associated with the first user account and based at least in part on the request to restrict presentation. A second instruction to present a second representation of the item of content is sent to a second computing device associated with the second user account, the second representation of the item of content being different than the first representation of the item of content.
