Greennet (previously) is the oldest ISP in the UK, tracing its origins back to Fidonet, where it was a hub for radical progressive political movements, which has attracted retaliations (in the form of DDoS attacks by repressive states) and surveillance (Greennet was one of the plaintiffs in a lawsuit against GCHQ over surveillance activities that ended with the spy agency "admitting clandestine hacking activities").

ISPs in US, UK, Netherlands and South Korea are suing the UK spy agency GCHQ over its illegal attacks on their networks in the course of conducting surveillance.
