We own a lot of "unique" sites with dedicated markets through out the US. Two sites in two separate markets have been getting hit hard with these DMCAs. No rhyme or reason to the content being suprezsed. In fact, the content is typically a decade old, paginated taxonomy, or ridiculously spamming page paths we don't claim.
Stakeholders receive the same notices I do and think we should care. I don't want to waste my time with the nonsense.
