The real responsibility lies with the recorded people who gave "apparent consent" to have their intimate and private acts to be recorded. Sometimes they even give their approval or give signs that they are aware of the recording device. Ex.: Girl giving thumbs-up to the camera while being pumped by her partner.
Also it is a different situation when there is "absolute consent" wherein couples/men/women willingly share to the public that private aspect of their lives. More often that not they use the cam themselves, and sometimes even in FB; they upload the material themselves. Ex. Guys these are my boobies, I am proud of them. (in a fictionarl FB post)
My advice to the TS is be specific in your accusations and charges like:
1. That is an underage adult content, so it should be banned.
2. That is my sister's sex tape. I asked her if she knew about it, I was told she was caught unawares. She is requesting for it to be censored and removed.
3. Or lastly, cite a legal issue. Ex.: That video is from a rape case now being heard in a Makati court. Please censor the identities of the individuals in this sex tape so that we won't be cited for contempt.
