Yep, another case of the FBI finding a 'terrorist' by finding a mildly disgruntled guy, giving him fake weapons and explosives, suggesting a terrorist plot to him, and then 'catching' him when he did exactly what they wanted him to do.

I imagine the first terms to be added could be something like "Company Confidential, Do Not Copy" or "Sensitive Business Information".

That said, copiers already block copying of certain patterns, such as US currency. With a little trial and error it's not hard to figure out exactly what on the dollar bill is being matched. Just add it to your documents, and no body will even be able to print them. (Careful, as some brands of printers will lock themselves and require a service call after you try to copy money.)

Um... what advertisements? There are no advertisements on that page that I see. (I even turned off my ad-blocker to be sure I wasn't missing any.)

Yes, the 100m limit was put in place to minimize the amount of time you had to wait to detect a collision, but it was also put in place when people hooked up a chain of computers to the same coaxial cable for their ethernet. Unless you are still using hubs, collisions aren't a huge problem, as the only thing to collide with is yourself. Use a switch and you can go above 100m easily.
