A giant hamster, a £520,000 fine, and a battle for regulation: What happens next for Ofcom and 4chan?

KWhen Ofcom fined US-based online forum 4chan a total of £520,000 earlier this year for failing to protect children from pornography and illegal content, the company’s lawyers responded with just a picture of a hamster.

“Mr. Whiskers eagerly awaits your consent decree, which will be used to disassemble and cover his enclosure upon receipt,” wrote Preston Byrne, who represents 4chan.

This wasn’t the first time the UK regulator had tried to force the forum to pay for alleged breaches of the Online Safety Act (OSA). It had tried to fine 4chan £20,000 in August 2025, and the forum responded by filing a lawsuit against Ofcom in the US courts (and telling them the paperwork would make the perfect bed for Mr Byrne’s pet hamster).

When Ofcom confirmed the £520,000 fine in March, Mr Byrne responded with an AI-generated image of a giant hamster wearing a Godzilla suit.

Although the responses appeared to be jokes, he insists in a blog post that they were “the most serious and important legal communication I have ever sent.” Their claims are simple; He says that because 4chan is based in the US, Ofcom does not have the authority to impose or collect fines and says: Independent any attempt to do so is “theatre.”

In response, Ofcom said it was willing to work with local law enforcement and courts to pursue overseas debts and had “initiated work” to trace funds owed.

On Thursday, the deadline set by Ofcom expires and it is clear that 4chan has no intention of paying the regulator.

Legal experts say Ofcom will now take action to block 4chan to UK users for the purpose of “sending a message”, but any action is likely to be “practically useless” as such blocks are easily bypassed by Virtual Private Networks (VPNs). 4chan, meanwhile, said risking the block was a price it was willing to pay.

Myles Jackman, a lawyer specializing in sexual freedoms and obscenity law, said the case exposed one of the OSA’s practical weaknesses: that the UK regulator “does not have the right to impose fines on US-based companies that they have no right to collect”.

“The UK government has no jurisdiction over the American Constitution,” he said, adding that Ofcom could decide to take enforcement action in the US because they have threatened it, but that “seems doomed to fail”.

He believes Ofcom will have no choice but to block 4chan on UK Internet Service Providers (ISPs) to protect its “credibility”, making the site inaccessible to users in the country. However, he points out that it will be easy to solve this problem for those who use a VPN.

More broadly, he suggests that the 4chan fight will be a “test case” for how effective such legislation can be, as well as having a “catastrophic” impact on foreign tech investment in the country.

“This is undoubtedly a test case for global regulatory overreach,” he said. “Without a catastrophic ban on VPN use in the UK, the regulatory regime would not work in practice.”

Nick Phillips, partner at law firm Edwin Coe, admitted it would be “difficult” to impose penalties on a company that has no presence in the UK.

But he said the OSA gave the government the ability to achieve its aim of protecting UK consumers by giving it the “nuclear option” of allowing users to block users from accessing 4chan, but conceded such action would do nothing to claw back the regulator’s money.

Concerns have also been expressed about what impact the powers granted to Ofcom by the OSA might have on foreign technology investment in the country’s economy. Mr Phillips said a number of smaller platforms had voluntarily left the UK market because they were deemed “too difficult”. But for him, this is a sacrifice that the government must make.

“I think the important thing here is the protection of UK consumers,” he said. “The OSA undoubtedly provides Ofcom with the tools to do this. These laws exist to protect UK consumers, particularly minors.

“You must apply these, otherwise everything becomes meaningless.”

A spokesman for Ofcom said it would seek to recover unpaid fines wherever possible “regardless of where the firm is based”.

“If they have assets in the UK, as ‘Big Tech’ companies do, the process is relatively simple and usually involves bailiffs obtaining orders from the UK courts to seize and sell UK assets in order to settle a debt,” a spokesman said. “If a company does not have assets in the UK, the process can be more complex and may require the deployment of debt collection and financial investigation experts, as well as local law enforcement agencies and courts, in the jurisdiction where the companies have assets.

“We started working to collect the debts of all companies that did not pay their fines on time.”

Mr Byrne said: “My client’s view is that the OSA’s deportation enforcement against this is theater. We are perplexed by Ofcom’s insistence on pursuing American targets who are not liable to pay any fines to anyone and who are engaging in perfectly legal and indeed constitutionally protected activities here in the United States.”

A government spokesman said: “Platforms have a legal duty to protect UK users under the OSA, regardless of where they are located. Services that fail to comply with the law may face enforcement by Ofcom, including significant fines and taking court action to block access to UK sites altogether.

“We expect all platforms to comply with their responsibilities under the OSA and have our full support for Ofcom to take action.”
