I am totally with you on this, and you are the perfect person to make the point. But there is a reason why these sites thrive. It is because sites like you used to have are few and far in between and not well known. Most of what is known and highly available is clips4sale, more or less the equivalent of a peep show where you put a quarter to see a little, or the very fragmented market of OnlyFans or IWC where you have to subscribe monthly to countless mistresses. I do not think that any of these offer good value for money.

If you would like to create a forum where you introduce the sites worth seeing, to my mind these being either aggregators or streaming sites I would not mind contributing a few reviews.

This account was registered the same day this post was made so I can't help but feel it's a bit of a bait post.
Regardless, I think this looked tame? I love Japanese femdom videos because they tend to be more far more harsh than American ones, and even a bit harsher than the European ones, the whipping in this video wasn't exactly "extreme violence" though.

And the FTT in this video wasn't anything special especially by Yapoo Market standards (the production series this video is from). The Japanese are really good at setting up fantasy in these videos and faking the brutality in a way that looks very real.
There's one Yapoo's Market video where a slave is trapped under a FTT chair with a bag seal, and all of the ladies piss into it until the piss is literally way above his head and they say he "drowned". Obviously that's not real, but the video is so convincing, I don't know how in the world they pulled that effect off.
