Udemy uses a proprietary player and attaches a Udemy watermark to all course videos. This is why, when you load a video to Udemy, there is both uploading AND "processing" time, because we are encoding your videos to make them difficult to steal.
But for a motivated pirate, any content that appears on a computer screen is vulnerable to theft. This is unavoidable and a problem across the industry. Giants like Netflix, Youtube, Amazon, etc. all have the same issue, and as an industry, we continue to work on new technology solutions to limit piracy.
Because pirating techniques currently outpaces protection, we hired a company who is specifically dedicated to enforcing the DMCA laws on your behalf and target violating individuals, hosting sites, and DNS servers in an attempt to get any unauthorized content removed. This company, Link-Busters, employs a team of professionals trained in DMCA law to go after piracy issues you bring to us. For more info on Link-Busters, feel free to take a look at their site: https://link-busters.com/
If you find your course on a pirate site, please submit a takedown request directly to Link-Busters using this form, making sure to include all the requested information.
Please note that because of the nature of piracy, many of these sites operate outside the law and are very difficult to get shut down, despite the best efforts of our team. Not every country has copyright laws and some pirate sites ignore lawful notices they are sent. That being said, Link-Busters will do its very best to try and get your content removed from the reported site.
