It is already technically posible to unmask a persons identiy even if anonymising sodftwere or services are used, as an example the tor network has been penetrated and wrongdoers discovered and appropriate action taken.
to understand how unmasking is actually acheived would require a book in itself to explain the possibilities so, to some extent the authorities" are already deeply embbedded in the system.
by their nature most VPN services are compromised by virtue of the fact tht a potential user is required to submit personal information (either directly or indirectly) to the provider.
however I'm only skimming the surface of how your identity can be compromised.
Turning to the legality of using such services it much depends where you are operating from, currently it is NOT an offence to use vpn seercies in the UK but this could change at any given moment. the question that should be upper most on your mind is the purpose for which you intend to use the service. and the changing political climate, todays acceptable use could be tomorrows "criminal" activity.
bear in mind also that your service provider can generally determine if you are using a proxy service ( especially so called hidden services), and the very use of such services renders you as " a potential person of interest" to the authorities.
My querie as to legality arose when I read about being able to access sites
anonymously and hide identities.
I wonder how much longer it will be before those in authority find a way of
stopping anonymous access of any kind?
