"Blocked" is one word covering four unrelated situations, and the reason generic advice on this subject rarely works is that it treats them as one. Before reaching for a tool, work out which wall you actually hit — the answer is usually visible from the error.
Four walls, and how to tell them apart
The resolver lied to you. The commonest ISP-level filter never touches your traffic; it just answers a DNS lookup with the wrong address, or with nothing, so the browser reports that the site cannot be found. This is the flimsiest block ever deployed and it is still the most widely used, because it is cheap for the network operator.
The network dropped the connection. A step up: the operator blocks the destination address, or reads the hostname your browser sends in the clear during connection setup and kills the session on sight. The page hangs, then times out. Corporate and school filters usually work here, often with an interstitial telling you which policy you tripped.
The site refused you. You reach the server fine and it declines to serve you — a region notice, or a landing page asking for age verification. Nothing is being intercepted. The site made a decision based on where your connection appears to come from.
The site left. A variant of the third, and the one people misdiagnose most. Several major platforms responded to state age-verification statutes by switching off access to entire US states rather than implementing checks. There is no block to route around, because there is no service there to reach.
The first two are network problems. The last two are policy, and they are the ones that grew.
What changed, and why it is a legal story rather than a technical one
The reason age gates are suddenly everywhere is two decisions roughly a month apart in 2025.
On 27 June 2025 the US Supreme Court decided Free Speech Coalition v. Paxton, upholding Texas's HB 1181 by six votes to three. The statute requires age verification from sites where more than a third of the content is sexual material harmful to minors. What matters beyond Texas is the standard the Court applied: intermediate scrutiny rather than the strict scrutiny used against a federal statute in 2004. That is a materially lower bar, and it cleared the way for the wave of state laws that followed.
On 25 July 2025 the UK's age-assurance duties under the Online Safety Act came into force, with Ofcom enforcing. The response was immediate and measurable: Proton reported sustained daily UK signup increases in the region of fourteen- to eighteen-fold, NordVPN reported roughly a tenfold spike, and half of the top ten UK App Store downloads that day were VPN or identity apps. Ofcom's first statutory report on age assurance later recorded more than 69 million age checks across a 32-service sample in the back half of 2025 — a step change, not a drift.
So the honest framing is not "how do I beat a filter". It is: this is now a compliance regime, most of the friction is a deliberate legal requirement, and the tooling question sits inside that.
What each tool actually does
Changing your DNS resolver defeats exactly one thing: the lying resolver. It is a two-minute settings change, it costs nothing, and against an address-level or hostname-level block it does nothing at all. Encrypted DNS extends this a little by hiding the lookup itself, but the connection that follows is still visible.
A VPN moves where your traffic leaves the internet. Your ISP sees an encrypted tunnel to one address, the destination site sees the exit server's country. That covers all four network cases and the region case, which is why it is the default recommendation — and why the demand curve moved the week the UK duties landed.
A proxy is not a smaller VPN. It relays traffic for one application, commonly without encryption, and the operator can read and modify what passes through. Most browser extensions marketed as VPNs are proxies. For getting around a lazy geo-check that distinction may not matter; for anything you would rather your network operator not log, it matters completely.
Tor works, is free, and is the wrong shape for this. It is built for anonymity, not throughput, and streaming video through it is both slow and antisocial toward a volunteer network carrying traffic that genuinely needs it.
The parts worth being straight about
A free VPN is a business, and if the subscription is not the revenue then the traffic is. The category has a documented history of logging, injecting and reselling — a paid provider with a published, tested no-logs position is a different product wearing the same word.
None of this makes an adults-only site suitable for anyone under 18. The age checks exist for that reason and the tools here do not change it.
There is a genuine privacy argument on the other side, and it is why a lot of otherwise indifferent adults went looking for a VPN in July 2025: verification usually means handing an ID document or a face scan to a third-party verifier you did not choose and cannot audit, in exchange for reaching a page. Preferring not to build that record is a legitimate position — though a VPN is a way to avoid creating the record, not a way to be invisible, and where a site has withdrawn from a jurisdiction entirely you are looking at its terms of service, not at a lock.
If you are shopping, the VPN listings here cover the providers by what they publish about logging and jurisdiction, which is the part of the comparison that actually varies. The connection speed claims mostly do not.
