I run the first site for phpBB hacks and the largest source of phpBB related downloads on the internet. There is a site out there that is using a script to harvest data directly from our database. Author name, version number, the .zip file, our description, the title, everything. Just taking it. No ethics, no morals, forget it. He's a scumbag. He's banned from my community.
Now, much of the content, I can't lay a claim to legally. The only possible thing I can is descriptions. In a lot of cases, descriptions are similar what authors provide with some help from myself. A capital letter here, a period here, etc. But, a lot of the time they are hybrid of what the author submits and what I write. In those cases, a lot of the time they are from the .zip file, so they are similarly GPL. But some of the time, they are not and some of the time I write the whole thing. In those cases, those descriptions are copyrighted to me. His host, however, has acted very unprofessionally - sharing my entire e-mails with him and telling him he's got "nothing to worry about."
... We added a new download last night and he ran his script today and now has it. I have worked for years to build my database on quality and on author permission and he is completely violating that work and everything that we stand for.
