The gpl-violations.org was a not-for-profit project founded and led by Harald Welte in 2004. It worked to make sure software licensed under the GNU General Public License was not used in ways prohibited by the license.
The goals of the project were, according to its website, to
- Raise public awareness of the infringing use of free software, and thus putting pressure on the infringers.
- Give users who detect or assume GPL-licensed software is being misused a way to report them to the copyright holders
- Assist copyright holders in any action against GPL infringing organizations
- Distribute information on how a commercial entity using GPL licensed software in their products can comply with the license." 
In May, 2008, gpl-violations.org and the Free Software Foundation Europe Freedom Task Force announced that they were to deepen their previous cooperation. The FSFE Freedom Task Force will be focusing on educating and informing, while gpl-violations.org will focus on enforcing the GPL.
The gpl-violations.org project was founded in 2004 by Harald Welte. Welte was a kernel developer who had been actively enforcing the GPL license on his netfilter/iptables code since late 2003. Since then, other developers have given gpl-Violations.org legal right to represent them. While the Software Freedom Law Center, an organisation with similar goals operates from the USA, gpl-violations.org operates from Germany, Welte's home country.
The project has been credited with being the first to prove in court that the GPL is valid and that it will stand up in court.
Project creator Harald Welte received the 2007 FSF Award for the Advancement of Free Software, partly because of his work on gpl-violations.org.
The website is offline and no longer resolving as of January, 2015.
In 2005, the gpl-violations.org project uncovered evidence that Fortinet had used GPL code in its products against the terms of the license, and used cryptographic tools to conceal the violation. The violation was alleged to have occurred in the FortiOS system, which the gpl-violations.org project said contained elements of the Linux kernel. In response, a Munich court granted a temporary injunction against the company, preventing it from selling products until they were in compliance with the necessary license terms; Fortinet was forced to make their FortiOS available free in compliance with GPL licensing.
On September 6, 2006, the gpl-violations.org project prevailed in court litigation against D-Link Germany GmbH regarding D-Link's alleged inappropriate and copyright infringing use of parts of the Linux kernel. The judgement  finally provided the on-record, legal precedent that the GPL is valid and that it will stand up in German courts.
