That's confusing...Since the site posts thumbnail for every video, it should be a real JAV site. And actually the latest update is yesterday(14th Feb.)......
Try more times or use "Contact us"...
It seems that i can't do anything even i know these website addresses now. I use a VPN to get a japan IP, but when i visit the websites, it comes "403 Forbidden". I have no idea about that!
Well, i have no problem using VPN to download from ryushare. What kind VPN do you use? Is there a dynamic IP address? That's probably easy to be blocked.
