19. The system of claim 14 , wherein the content consumer user profile is a first content consumer user profile, and wherein the at least one processor is further configured to execute the computer-executable instructions to: receive a request for annotations associated with the content from a third user device associated with a second content consumer user profile; determine that the second content consumer user profile is associated with the first annotator user profile; and send the annotation data object to the third user device.
14. A system, comprising: at least one memory storing computer-executable instructions; and at least one processor communicatively coupled to the at least one memory, wherein the at least one processor is configured to access the at least one memory and execute the computer-executable instructions to: receive an annotation data object from a first user device, wherein the annotation data object is associated with a first annotator user profile and comprises an annotation of content and anchor data indicating a location of the content within a content item; determine that the first annotator user profile is associated with a content consumer user profile; assign a priority designator to the first annotator user profile indicating a first priority for presentation, to the content consumer user profile, of annotations associated with the first annotator user profile in relation to a second priority for presentation of annotations associated with a second annotator user profile associated with the content consumer user profile, wherein the first priority for presentation is based at least in part on a type of association between the first annotator user profile and the content consumer user profile, and wherein the first priority for presentation is higher than the second priority for presentation; apply a content filter to the annotation; and send the annotation data object to a second user device associated with the content consumer user profile.
