See, I still think that's innocuous since it does not list any particular infringing links. For example, Google has no issues showing us opentrackr.org.

And yet, it is completely absent from the DMCA takedown, which signals to me that they really did no work at all before making this takedown.

a link to a list of trackers it no more illegal than publishing the public street address of a business that sells products that are illegal in certain jurisdictions (texas dildo law, anyone?)
