Recent news suggest online based platforms such as Sindome and other media which lack sufficient age gates may be subject to vast fines. Is Sindome at risk?
But to comply is also not extremely complicated, you just have to show good-faith checks being carried out to prevent minors from using the service. This really can be as simple as requiring a date of birth to be inputted before accessing the website or making a new account. That and small updates to sindome TOS, but you would need a lawyer for it.
I'd defer to an expert on this topic but on its face that appears to be a pretty serious burden. Maybe we should be blocking UK IPs just to stave off problems.
