As publishers turn from print to digital and rely on online ad sales, some websites now prevent readers from viewing content if they have an ad blocker enabled. Alexander Hanff, a privacy activist and CEO of Think Privacy, has launched a campaign to “name and shame” publishers using these methods. The campaign announcement comes days after the European Commission stated in a letter addressed to the activist that ad blockers can be illegal and in breach of EU privacy rules.
The mechanism to detect ad blockers appears to require access to personal data. The campaign encourages internet users to report websites circumventing ad blockers to prevent publishers from infringing on personal privacy. Hanff says he will bring legal challenges against sites using anti-ad blockers without prompting for user permission.
