Political advertising is meme based.

So the technique is for anons to compose libraries of all the possible political memes and use their copyright to shut down political advertising.

Political parties can draw up meme libraries of all their opponents possible memes and close down their opponents advertising.

Anons can draw up libraries of all possible memes for commercial advertising and use that copyright to shut down commercial advertising.

What is needed is a crowd funded internet copyright meme library.

As Q would say; "These people are stupid"
