The ironic thing is the news of Maddona saying “what the fuck do you think you’re doing!” in a loop made me seek out that mp3 
And the way some are set up like winMX,the files your host is sharing and your own files can get their names confused.
Thats why you will see Evanescence-Bring me to life.mp3 and the file size is 700Megs.
You will also get “ghost” files it appears you’re sharing when you aren’t.
So a lot of these networks are not bug proof,but still some of what you’re asking about is probably good old fashioned asshatish stuff.
