Wikipedia, Reddit, Imgur, et al.

They often are only blocked for hours at a time but it is still heavily disruptive.

Was the whole domain blocked or the individual resource?

They all seem like examples of things that English law would block - mostly images of child sexual abuse or images of human-animal sex.

If someone is blocking all of WP and not the individual problem page then yes, that is stupid and annoying and I agree with you.
