Ah, brings back memories when TPB did something similar to when MPAA and their "associates" emailed them. I think this is probably the best page where one could still see them: https://web.archive.org/web/20111223101839/http://thepirateb...

I'm not sure it helped in the end, afaik they did it since like 2003 until some years after the raid, but it still seemed like they didn't get the message and kept trying anyways, which from their perspective makes sense but still.
