Imgur were found to be in breach of the data collection laws before any "you must check IDs" laws were even discussed in parliament, let alone passed, where the guidance was pretty much "Don't get caught actively selling data you already know is from children". And even the punishment was pretty much writing a document of "we'll try not to do it quite so obviously next time", but they refused to do even that.

The "implied" link between their fines, them rejecting UK connections, and any new laws is very much a PR thing from imgur.

All the breathless online reporting seems to miss just how toothless the law was, and they still failed at following it.

Like I think the new verification laws are an unworkable mess at best, written by people with an idea similar to believing they could "ban one specific species of fish from UK territorial waters" by throwing the odd grenade in, but they're rather unrelated to what imgur actually did.
