Systems and methods for restricting content inserted into information resources are provided herein. A data processing system can identify a first content element on an information resource. The first content element can have a first bit stream. The data processing system can determine an interference to a rendering of the first content element on the information resource. The data processing system can generate, responsive to determining the interference, a second content element for a subsequent information resource based on the first content element. The second content element can have a second bit stream different from the first bit stream. The data processing system can transmit, the subsequent information resource including the second content element to the client device. Receipt of the second content element can cause a content restriction script to apply a rendering-based restriction policy responsive to the second bit stream differing from the first bit stream.
