Look at the screenshot. Each row has a filename and a hostname that is downloading the filename.


This is a one-client operation. It already knows who you are (screenshot). Bingo, cache conversion date.
Not realy. The Unity is the cache. Perfect Dark is designed so that every single client caches random files. Just because something is in your Unity it means nothing since you have absolutely no control over what it is being downloaded, with the exception of the files you selected. PD is designed in this fashion in order to provide "plausible deniability" among other things.

Perform this experiment. Start a brand new install of PD. Don't search anything. Don't download anything. Just connect and let it be. You will see that the Unity begins to fill-out by itself.

However, the point is that by looking at the Unity there is no way to know if the file is one that you selected or Perfect Dark downloaded and cached automatically. The ONLY way to know that is if you decrypt the file. However, Perfect Dark allows for the erasure of the info regarding downloaded files and decrypted files. This info is NOT stored in Unity but in a separate database. You *CAN* erase this info selectively from the Download screen -as far as I understand it-.

Of course, PD won't delete the encrypted file from Unity, but, once you deleted the reference to download/decryption, there is no way to know if you did or did not download it. In other words, the file is "in the network". Therefore, and to my point, if there would be a way to either NOT record the fact that you downloaded a file or decrypted a file, there is no way to know if it is "YOUR" file or "PD's". Therefore, not a big deal. Bottom line, removing this info, the crawler is actually providing very little info other than knowing that you are on the network and finding which files are also on the net. So what? This is roughly the same info you can get by just installing the client and doing a search. From a legal standpoint, in this scenario for example, there is no way to prove that you downloaded a file versus that PD did it automatically.
