> Twitter, Reddit and image-sharing community Imgur, for example, will not be required to administer the scheme because they fall under an exception where more than a third of a site or app's content must be pornographic to qualify.
Likewise, any platform that hosts pornography but does not do so on a commercial basis - meaning it does not charge a fee or make money from adverts or other activity - will not be affected.
Furthermore, it will remain legal to use virtual private networks (VPNs), which can make it seem like a UK-based computer is located elsewhere, to evade the age checks.
