Abstract: Systems and methods for responsive modification of electronic content are provided. In one embodiment, a moderator application executed by a processor accesses electronic content and provides the electronic content to a first client. The first client is restricted to accessing a first portion of a displayed area or frame sequence of the electronic content. The moderator application restricts the first client to performing only a first subset of modifications to the electronic content. Responsive to the first client performing one of the first subset of modifications, the moderator application provides the electronic content to a second client. The second client is restricted to accessing a second portion of the displayed area or the displayed frame sequence of the electronic content. The moderator application restricts the second client performing only a second subset of modifications to the electronic content.
