A Leeds man tired of cold callers made his own phone number cost money to dial — using the exact billing system built to profit off consumers like him

the problem

An individual has no practical legal recourse against unwanted calls from companies that bought or scraped their number, and blocking technology only prevents the call, it doesn't discourage the caller

background

what everyone would do

The available consumer tools were purely defensive — blocking a caller's number, registering with a do-not-call list, filtering unknown numbers — all of which only prevent a given call from getting through, without imposing any real cost on the companies buying or scraping his number and dialing it in the first place.

what they saw

Beaumont saw that blocking only addressed one call at a time while doing nothing to the incentive driving telemarketers to keep calling, since dialing him cost them nothing regardless of how many numbers he blocked. The existing UK premium-rate billing infrastructure was already built to charge callers money for reaching someone, just normally deployed by businesses against consumers — so instead of building a new defense, he simply redirected that exact system, putting himself on the receiving end of the fee rather than the paying end.

the move

In November 2011, Beaumont spent about £12 to set up his own 0871 premium-rate number and gave it out as his contact number instead of a standard line. Callers were charged 10p a minute, of which Beaumont received 7p and the hosting company kept 3p — so every company that called to sell him something now had to pay him by the minute simply for the chance to pitch him, using the same billing infrastructure normally deployed against consumers.

why it works

Setting up his own 0871 premium-rate number and giving it out as his contact line meant every company that called him now had to pay 10p a minute for the chance to pitch him, flipping a billing relationship consumers normally only experienced as a cost into one working in his favor, using infrastructure that already existed and required no new technology or legal action to deploy. Because the cost now fell on the caller rather than the recipient, telemarketing firms had a direct financial incentive to stop calling once word spread that his number was expensive to dial, which is why his monthly call volume dropped from over 30 to roughly a dozen — the fix changed the callers' own economics rather than merely blocking their attempts. The setup cost him only about £12, recouped within two months, meaning the intervention was disproportionately cheap relative to the ongoing nuisance and mounting call volume it addressed.

the payoff

Beaumont recouped his roughly £12 setup cost within two months and, at his peak, reported earning around £7 a month from cold calls alone; more strikingly, his monthly volume of unsolicited calls dropped from over 30 to roughly a dozen once word spread among telemarketing firms that his number cost money to dial, with £300 in cumulative earnings reported by the time BBC Radio 4's 'You and Yours' covered the story in 2013. The UK premium-rate regulator, PhonePayPlus, publicly discouraged the practice and warned it could pursue complaints against both Beaumont and his hosting provider.

where it breaks

The mechanism depends on there being an existing piece of monetization infrastructure genuinely available to redirect — a channel with no built-in fee-collection mechanism (email, most messaging apps) offers no equivalent lever to flip, meaning the specific tactic doesn't generalize to every unwanted-contact channel without first finding or building an analogous billing layer. It also depends on regulators and hosting providers tolerating the arrangement: UK premium-rate regulator PhonePayPlus publicly discouraged the practice and warned it could pursue complaints against both Beaumont and his hosting provider, showing the tactic operated in a regulatory gray area that could have been closed off entirely. And the deterrent effect depends on callers actually noticing and reacting to the cost before dialing — the calls that did get through still charged Beaumont's own reputation and contact number as a public-facing '0871 line,' a tradeoff that would be unacceptable for anyone whose personal or business number needed to look conventional to legitimate callers.

what came after

Beaumont's story was widely covered by the BBC, The Register, Fast Company and other outlets in 2013 and is cited in consumer-technology and behavioral-economics writing (including a Freakonomics blog post) as a folk-hero example of an individual redirecting an asymmetric billing system built to extract money from consumers back against the businesses that relied on it.
