The fight against theft of content on the Internet

What can be proposed ways to combat theft of content on the Internet, where many people use this method to some extent (clean copying, or rewriting).
Even such respected publications as RBC and Vedomosti do not disdain it (remember, there was a scandal some time ago), then what about the sites of lesser-known companies, or just information sites?

What if to create an online archive, where any person or company could place their article / news / story, etc. for a small fee? This text will be stored there, along with the date when it was entered, and used later in solving controversial issues related to copyright.
Of course, at the beginning this service will be known to very few people and will not be authoritative, but over time it could receive the status of an independent arbitrator in the field of copyright.

This service will not be cluttered, as the database of search engines, since the introduction of each article will be paid. Also, this service would be indispensable for sites that exist only in the electronic version and can not produce printed versions (thus protecting themselves from illegal copying).
