I’m not convinced this is the reason for the Imgur block. They were asked by the UK about how they processed the data for minors at the start of the year. They refused to provide it, and were then fined. When the age check was implemented I think they used that as an excuse to block the UK, so they “weren’t operating in it” and didn’t need to answer the questions.

The UK gov disagrees with that and is planning more legal action iirc.

If they had done the block without that law, people would be asking why they were not revealing how they process data of minors.
