You guys do what you feel is acceptable. Myself I don't condone paying any amount of money to buy leaks. The leakers obtained them by illegal (theft) and unethical (commercial non-disclosure contract) ways. And of course it's also violating copyright. I'm a very morally flexible guy, have been pirating JAV for years. Even leaks, I do collect them, but that's right about the red line. If these bad people get any benefit from my collecting I wouldn't do it.
Most importantly leaks are very hurtful to JAV idols. A lot of people think it rather strange that some performers have done these nasty sex for the camera and now are complaining her pubic hair is exposed on the internet. Yes it may be strange logic, it does not matter. What matters is what JAV idols themselves wants or feels. They want to maintain that last region of privacy, I have to respect that, no matter how illogical it is. Yes yes I'm very contradictory, I feel bad that idols are hurt by leaks but I also chase down every leak that I can find. But my red line is whatever I do, is not encouraging leakers to do more of it.
A lot of your new guys don't know this: when the first wave of leaks was unleashed it was a very bad atmosphere for JAV. New girls don't want to join the industry and several top veterans retired. How many was caused by the leaks were unknown. At the very least Ayami Shunka (one of my favs) retired due to the leaks. I wish the JAV industry (and JP gov) would wake up and make dicks and pussies legal on screen, but that's a whole different topic. For now, I want to find all the leaks that come out in the wild, AND I want leaks to stop, at least slow down a lot.
