Hello, How do you think VPN providers that claim to not log customer activity (such as session times) combat abusive users? Let's face it abuse levels are high when you run anonymity networks and there is a lot of abuse such as SPAM (not just SMTP spam but blog/forum/web mail). The underlying ISP's VPN providers use to host their servers have TOS's that prohibit the likes of SPAM from being sent, and VPN providers must maintain a good relationship with the ISP's they use to ensure they do not lose their server contracts. Simply ignoring SPAM complaints will lead to server disconnections. Sure there are some VPN providers who run their own networks, but the majority of 'non-log' providers don't; that said continual complaints will start to filter through to their upstream providers. I put this question to a number of VPN providers who do not log, in particular Astrill and Witopia, and both claim to have this 'top secret' method of being able to locate abuse without logging customer sessions, they of course wouldn't tell me what kind of methods but assured me they were able to locate abuse. This worries me. How do you think a provider can identify abuse if they are not logging? It sounds to me they may be sniffing customers connections.
