9. One or more computer-readable media devices having computer-executable instructions embodied thereon, that when executed by a computing system having a processor and memory, cause the computing system to perform a method for identifying a scripted item within content requested by a user, the method comprising: receiving, at a server, a request for content from a user, at a user computing device; determining, at the server, a first hash value for a scripted item of the content, wherein the first hash value is based on a hash function and the scripted item; applying, at the server, the first hash value to the scripted item; determining, at the server, a second hash value for the scripted item, wherein the second hash value is based on the hash function and the scripted item; determining, at the server, the scripted item is not proper based on the first hash value and the second hash value; and in response to determining that the scripted item is not proper, preventing communication of the scripted item to the user, wherein preventing communication of the scripted item to the user comprises at least one of: (1) altering the scripted item to prevent execution of the scripted item by a computing device associated with the user, or (2) removing the scripted item from the content.
