It seems media defender are out to get some publicity folks as their market shares are not holding up due to more folks knowing how to deal with them, also it marks the start of a return to their older methods of attack, they are trying the old half a file trick, so folks get frustrated with p2p, this cost them a lot of effort compared to normal fake flooding. You can see why their share price is dropping now.

Decoying. This, in a nutshell, is the serving of fake files that are generally empty or contain a trailer. The goal is to make legitimate content a needle in a haystack, so MediaDefender works hard to ensure that its copies of files show up in the top ten spots when certain keywords are searched for. Everything about the file is tailored to look like the work of pirates, from the file size (movies are often compressed enough to fit on a CD) to the naming conventions to the pirate scene tag. With massive bandwidth and plenty of servers, the company has little trouble in getting these decoy files to appear at the top of search results, but decoying has a down side: the bandwidth. Because MediaDefender actually serves these large but bogus files, it incurs a significant bandwidth bill by using this technique.
Spoofing. Spoofing sends searchers down dead ends. MediaDefender coders have written their own software that interacts with the various P2P protocols and sends bogus returns to search requests, usually directing people to nonexistent locations. Because most people only look at the top five search results, MediaDefender tries to frustrate their first attempts to download a file in hopes that they will just give up.
Interdiction. While the first two techniques try to prevent searchers from locating files, interdiction prevents distributors from serving them. The tool is generally used when media is leaked or newly released; the goal is to slow its spread in those crucial first days. MediaDefender servers attempt to create constant connections to the files in question, saturating the provider's upstream bandwidth and preventing anyone else from grabbing the data.
Swarming. Though he acknowledges the BitTorrent networks can be hard to disrupt, Lee points out that MediaDefender can use "swarming" to make life more difficult for users trying to download copyrighted content. BitTorrent works by using a hash file to reassemble a file from many pieces, each of which may have been downloaded from a different user. MediaDefender simply serves up its chunks of these files, but instead of providing the proper data, its chunks contain static or nothing at all. When the file is eventually reassembled by the user, it may contain clicks, silent spaces, or odd skips. This can make the viewing/listening experience less pleasurable, but it's most effective with software downloads since even small errors can prevent programs from running
These idiots may sell their products to businesses that are not tech savvy but here on mx they haven't a chance to pretend they are causing problems, using the winmxgroup patch puts all their hard work into the trash
