Ads don't work so websites are using your electricity to pay the bills
Pirate Bay and Showtime turned to forcing unknowing visitors to mine cryptocurrency, using computers rather than 
eyeballs on ads to generate money

With the continuing collapse in online advertising revenues, websites are turning to other methods to pay their 
hosting bills – including using visitors’ computers and phones to mine cryptocurrency.

It’s a controversial practice, with some likening it to running malware on visitor’s computers, but it is a 
potentially lucrative endeavour for websites. The downside is that at best it slows down visitors’ machines, and at 
worst it can also drain their batteries or send their electricity bills soaring.

BitTorrent search engine The Pirate Bay, and US video streaming service Showtime, are two sites that were discovered 
to be sending mining code to users. The former owned up, posting in mid-September that the code was “just a test” and 
that the experiment was being done with a view to removing all adverts from the site.

The latter removed the code on Monday, shortly after a user noticed it and specialist press began reporting. But it 
has yet to answer questions on why the code was there from the Guardian and other media organisations.

Cryptocurrencies, such as bitcoin and its successors, are backed by a system of “miners”, who race to be the first to 
solve tricky computing problems in exchange for a reward for doing so. The rewards are large – the bitcoin network, 
for instance, gives away coins worth $7m to miners every day – but to be in with a chance, miners need to gather an 
extraordinarily large amount of computing power.

Not only is it expensive to buy those computers, it also consumes a huge amount of electricity to run them. As a 
result, the most profitable mining companies often have access to cheap energy, or some other efficiency boost - one 
firm, based in Iceland, saves money by letting the country’s naturally cold climate cool its computers.

Website-based mining short circuits that: the electricity bills are paid by the visitor, but it’s the website that 
gets the reward. 

“Gaming and video sites typically are more resource intensive, so it seems to make little sense to run a miner at the 
same time without having a noted impact,” says Malwarebytes analyst Jérôme Segura. “Having said that, many people who 
consume copyrighted content are perhaps less likely to complain about an under-par user experience. 

“The question at this point is: how far can publishers push the limits towards a really bad user experience? You may 
be surprised that for many, this is not really a problem at all and that double dipping is, in fact, a fairly common 
practice,” he added.
