Violations of the GPL, LGPL, and GFDL
原文：
http://www.gnu.org/licenses/gpl-violation.html
If you think you see a violation of the GPL (or the LGPL, or the GFDL) the first thing you should do is double-check the facts:
Does the distribution contain a copy of the License?
Does it clearly state which software is covered by the License? Does it say anything misleading, perhaps giving the impression that something is covered by the License when in fact it is not?
Is source code included in the distribution?
Is a written offer for source code included with a distribution of just binaries?
Is the available source code complete, or is it designed for linking in other non-free modules?
If there seems to be a real violation, the next thing you need to do is record the details carefully:
the precise name of the product
the name of the person or organization distributing it
email addresses, postal addresses and phone numbers for how to contact the distributor(s)
the exact name of the package whose license is violated
how the license was violated:
Is the copyright notice of the copyright holder included?
Is the source code completely missing?
Does the written offer for source, if given, only give a website and/or FTP site where to download the source?
Is there a copy of the license included in the distribution?
Is some of the source available, but not all? If so, what parts are missing?
The more of these details that you have, the easier it is for the copyright holder to pursue the matter.
Once you have collected the details, you should send a precise report to the copyright holder of the packages that are being misused. The copyright holder is the one who is legally authorized to take action to enforce the license.
If the copyright holder is the Free Software Foundation, please send the report to <
license-violation@gnu.org>. It's important that we be able to write back to you to get more information about the violation or product. So, if you use an anonymous remailer, please provide a return path of some sort. David Turner <
novalis@gnu.org> presently answers this address; GPG-encrypted mail may be sent to <

Note that the GPL, and other copyleft licenses, are copyright licenses. This means that only the copyright holders are empowered to act against violations. The FSF acts on all GPL violations reported on FSF copyrighted code, and we offer assistance to any other copyright holder who wishes to do the same.
But, we cannot act on our own if we do not hold copyright. Thus, be sure to find out who the copyright holders of the software are before reporting a violation.
如果发现违反GNU GPL, LGPL, FDL的行为，你该怎么做
中文翻译原文：

如果您认为您看到了对于 GPL （或 LGPL 或 GFDL）条款的违反时， 您应该要做的第一件事就是再次确认这些事实：
这个散布件（distribution）是否包含『许可证』的一份副本？
它有没有清楚地陈述哪一个软件被涵盖在『许可证』？ 它是否有说任何使人误解， 也许给人某件事是被涵盖在『许可证』， 但是事实上却非如此的事？
源码（source code）是否被包括在散布件中？
与散布件包括在一起的源码书面提供是否只有二进制档？
可取得的源码是否完全， 或是它是否设计来与其他非自由的模组（modules）连接？
如果看起来似乎是真的违反， 您所需要做的就是仔细地记录〔所有的〕细节：
那项产品的精确名称
散布它的个人或组织的名称
如何联络散布者的电子邮件位址、邮政位址和电话号码
违反『许可证』的包的确切名称
『许可证』如何被违反：
是否包括版权所有者的『许可证』声明？
源码是否完全找不到？
源码的书面提供（如果有的话）， 是否 只 有给可供下载的网站， 并且／或 FTP 站？
是否于散布件中包括有『许可证』的一份副本？
是否只能取得部份而非全部的源码？ 如果是这样，哪些部份缺少了？
如果您提供愈多这些细节， 版权所有者就能愈早处理这件事。
一旦您收集了这些细节， 您应该送一份报告给被错误使用的包的版权所有者。 版权所有者是经由法律授权的可以执行『许可证』〔法律强制〕的人。
如果版权所有者 是 自由软件基金会（FSF）， 请将报告送到 <
license-violation@gnu.org> 。
注意到 GPL 和其他的 copyleft 许可证， 〔都〕是版权许可证。 这表示只有版权许有者才有权利对于违反采取行动。 FSF对于所有 FSF 具有版权的代码（code）的违反报告采取行动， 并且我们〔也〕提供协助给任何其他想要这样做的版权所有者。
但是， 如果我们并不拥有版权， 则我们无法独立地采取行动。 因此在报告一项违反时， 请务必先确定谁是软件的版权所有者。
