They didn't ignore it, they are very familiar with the terms. What they can do depends on if the government ends up classifying them as a warez site or a library/archive. And, if they are a library/archive, if their actions can be considered part of the copyright exceptions.
The publishers lawyers will argue they are just a warez site, and use everything in their power to do such, jurisdiction, case law, confusing terms and obfuscation, etc.
