None of the client data is from my downloads. All the client data is from me uploading to other people only.

If I am uploading then they are downloading, right? So I am uploading to them and they are downloading from me. And if I was downloading from them, then they would be uploading to me. What is wrong with that? How do you say it?

What is wrong with saying "downloading from me?" They are downloading a file, and I am the one that they are download it from, so they are "downloading from me."

"2. The "data" is not the "18.5 gigs" that I uploaded, it is the data that I collected about those people that downloaded from me, i.e. what client & version they were using, what country, IP, host, time of day, etc."
This is the "downloading from me" that you are talking about right?

Here what about this?
Arrow = data flow
my downloads - Me <-- Them
my uploads - Me --> Them
downloads from me - Me --> Them
uploads to me - Me <-- Them

So is that wrong?
