You can send DMCAs to pornbb and they'll actually delete threads. But don't do this until you've sent the DMCA to the filehost otherwise the files are still available. Pornbb is slow and doesn't always carry through with it, but most of the time they will. Even if they don't remove the thread, if the uploader re-ups the content it will bump it to the top of the forum so that you should be able to catch it again. If they don't remove the thread and you kill the links, then at least the post sits there with a few screenshots, almost like an advertisement. Just make sure that they can't find that movie in another thread.

And before you take on pornbb you absolutely must install the CCF container format decrypter. It will decrypt all the container formats that pirates use to mask URLs.

Almost all the posters on pornbb post the same links on 5 or 6 other forums as well, but you can use pornbb as a nice net to catch the majority of uploaders. They post to pornbb because it gets the most traffic and they need LOTS of downloads to meet the payout thresholds from filehosts.
