This is what I found on the TSR front page news :

Myth: TSR place trojans in their downloads to gain information
The Story: In the early days of the Pirates and pay content file sharing, we put watermarks on the files at the point of downloading. This simply applied the TSR user ID, IP and time/date to the .package file of the downloader, so that we could take the files from the booty and see which user shared it. This was done server side, our end. It gathered no information about the user once they downloaded that file. This hardly constitutes a Trojan or virus.
The Fact: TSR, as a professional business, has no desire to add malware to its downloads and takes no part in such activities. The Pirates didn't like that we were on to them so cooked up this story because at the time they didn't know how we were catching them. They hated it even more when they found we used their own shared files against them! Of course they now know, but wont retract their claim because it adds too much value to their smear campaign.
Wouldn't this mean that TSR is still catching file sharers even from the booty even thou it's being cleaned?
