Thank you, as an AirVPN co-founder I am very proud whenever I come to know that AirVPN has been immensely useful thanks to its mission. Compliance to the mission is what made AirVPN immensely useful to so many people around the world.
What you propose is potentially a betrayal of the mission and would bring us to a slippery slope: once you start monitoring, you open a Pandora box which may become quickly destructive. The matter must be approached carefully as your reasoning is even the rationale which is bringing the EU to an attempt to ban end-to-end encryption in chats etc. https://www.eff.org/deeplinks/2022/10/eu-lawmakers-must-reject-proposal-scan-private-chats
Consider that the alleged infringements we come to know from IP address black list compilers are a negligible percentage (something around ~ 0.1%) over the total amount of sessions and users of the service. It means that the infringers amount is not greater than the general amount of civil or criminal infringers in the society, i.e. every year in every EU country at least 1 citizen out of 1000 infringes civil or criminal laws outside the Internet (and that's only the ascertained amount of infringements).
Many blocks you experience are not even caused by infringements committed intentionally, but simply by infected computers. Several black list compilers just add IP addresses, or even IP address ranges, after a simple, unverified claim by literally anybody showing a text log. So the VPN server might have done nothing, but its address is black listed anyway because in the past, from an IP address in the same range or assigned to the same ASN, some infringement was alleged.
Then web site administrators add black lists in the dangerous illusion of adding security to their sites. It is an illusion according to stats which show that the amount of successful web site breaches has not decreased in the last 5 years, and in reality it is just a, often unaware, step to indirectly jeopardize privacy, because it will push some users to ask for more surveillance and privacy intrusions by their own provider in order to have a "clean" IP address (exactly what you have done here):
Kind regards
