The number one rule about VPN's is that you should assume they are all entirely compromised. The second rule is that you should keep in mind asking for a VPN on a site like SR is essentially asking the feds if they would like your IP address. That said, JAP seems to be above average as far as VPN providers go. They will immediately start logging as soon as they get a court order to log traffic to a particular site or from a particular user, but they give you two or three hop cascades so usually two different court orders in two different countries are required. And they are very strict about not logging anything until they get a court order forcing them to do so. That is pretty much the best you can hope for. Or you could go search around for some sketchy Russian service and buy a VPS from them. Personally I would be more inclined to buy a VPS to exit through if I wanted to have an exit IP address that didn't identify me as someone using an anonymity service. VPN services have their IP addresses on many of the same block lists as Tor exit nodes do.
