Trestor, if people have renamed files they downloaded from winmx to strange filenames then the same will apply as above..
the hash is the same, so if their strange named file matches a file you are trying to get then winmx wont care about the name and connect you to that user..
Many users may simply get the files that way, too.. and have not gotten around to renaming the files yet, various websites supply the files this way..
Especially when the file is Asian and 'had' originally an Asian title.. Asian characters don't work well in web addresses such as http://somesite/
哈哈哈.mp3 so they replace the characters with numbers..
