Judge: Salem Library can't block website content; Library says lawsuit changes nothing

[Knightraven]

2. This story is odd to follow.

The lawsuit said Hunter was trying to do research at the library but filtering software blocked access to sites about things such as Wicca, a pagan religion that worships nature and involves witchcraft.

The consent judgment lets the library to keep up its good work for its patrons and continue the fine balance of the public interest in open access to information with the library's legal obligation under the Children's Internet Protection Act.

Now I understand some pictures may be blocked due to the law, however why did they have the whole topic blocked? I understand that they did go ahead and fix the issue, yet why block the whole topic in the first place?

Then I also saw that the story said:

This is the same internet screening service provider as ninety percent of public libraries in Missouri.

Is this type of block used widely?
