Prominent backbench MP Sarah Champion launched a campaign against VPNs previously, saying: “My new clause 54 would require the Secretary of State to publish, within six months of the Bill’s passage, a report on the effect of VPN use on Ofcom’s ability to enforce the requirements under clause 112.
"If VPNs cause significant issues, the Government must identify those issues and find solutions, rather than avoiding difficult problems.” And the Labour Party said there were “gaps” in the bill that needed to be amended.
They’re going to know it’s VPN fairly easily because it’s fairly obvious what you’re doing when all or most of your traffic is encrypted and is directed at one or two addresses. Even more obvious if those one or two addresses happen to belong to known VPN or VPS providers or something.
