It was in italics as it was a direct quote. Stop bunching your knickers.
Quotation marks are the accepted standard for indicating quotes. Furthermore, a quote is not complete unless accompanied by a reference to the source. The whole point of a quote is that it's somebody else's words, and if nobody knows who else's words they are, we can only act under the assumption that you intend to back them up yourself.

Following the succession of links from here, I can see that you quoted a quote of a quote of a 404. Cool primary source, bro.
The last quote in the chain before hitting a 404 still doesn't explain exactly what is meant by "transmitting". Furthermore, it makes the claim that "The computers were identified by GUID (a unique serial number), not IP addresses", without any explanation of which piece of hardware (or software) that GUID refers to, how those GUIDs were discovered or how those GUIDs were mapped to physical locations.
Not only does my point stand, but you have raised even more questions in your attempt to address it. Please, spare us all the trouble and pick a real source next time.
