I'm paranoid but not an android. Harmful. Brings unwanted attention. Just like Narutofan (or whatever was that site that sells fansubs for profit). I want to enjoy fansubs till the day I die, and so better careful than sorry sounds good to me.
Well, to be realistic I don't know how much it matters. And nothing can be done about it, anyway. Fansubbers can't defend their rights, even if they wanted. They do have copyrights to their translations, but not even to the information their translations contain, not to mention the video and audio they distribute. So, they couln't do anything about somebody uploading their efforts. And besides, they are all just against selling their translations, not distributing them for free.
Yet I can't understand why anybody would want to watch the series in stamp sized, uber low quality 15 mins clips (or are they ever that long?).
