Here are some general suggestions as to how NOT to download gross KP.

One of the most effective methods I've found when searching for and DLing vids (of whatever kind) is to search for vids only, and then to sort the results by descending size (i.e. biggest files on top). When you're talking about videos, it's unusual for anything below 8 MB to be legit, especially when the vid is longer than 5 minutes or so. I don't touch anything below 10 MB. KP I've found accidentally is almost always in smallish files.

Also, in terms of what to do when/if KP is accidentally downloaded, there's a program called Eraser that's free and is designed to securely empty your recycle bin (by erasing it), as well as erasing empty disk space. In other words, when you delete something normally, there is still a "trace" of it, unless you fill the space on the drive with other stuff. Eraser overwrites all empty space on a drive, effectively wiping out any trace of anything that may have been there.

Whether or not I surreptitiously downloaded any KP, I Erase on a regular basis. It's just smart to do (I think). I find these simple yet effective steps help me to sleep better.

LimeWire and P2P in general are some of the last bastions of total freedom we have left. Let's not let the less-than-nice side of it, putrid as it may be, ruin all the greatness for everyone.
