I remember those dioguitar23 twats! I'm pretty sure those parasites get their stuff for free as well. they were mostly "refugees" from an old taiwanese board called Waikeung BBS. not sure about these days, but they used to leech from two incarnations of a japanese board: Alabout, which back in 2006-2009 were mostly japanese, and ocassionally taiwanese posters who post their own rips.
I spent most of my time on their old board until the same clueless fuckwits invaded and started re-encoding stuff that was posted there and usually via ad/revenue generated links. the whole situation got so bad even the admins couldn't deal with it. Many rippers consequently either slapped their OWN name on it or they just gave up, like i did.
In contrast, nobody who post EU/US AV releases on EU/US torrent sites does the same thing!
