"We provide our services strictly for non-commercial use, in order to provide support exclusively to individuals or groups we feel we have an affinity with. In order to verify the existence of these pre-conditions, each and every service request is processed manually by one of our volunteers and is in a dialogical form. All requests are anonymized and will be destroyed."

Anonymized how? Before the first contact? After the conversation?

If anyone here wants to set up a similar service: This is patently stupid for an ISP to attempt.
