It’s unfortunately the case that software development in general and Open Source communities are frequented by males who have social development issues. I once complained online about how offended I was by a news story that said many software developers were on the autism spectrum. To my embarrassment, there were many replies to my complaint by people who wrote “no, I really am on the spectrum and I’m not alone here”.
.. Online communities like those hosting Open Source developers tend to use textual communications. This is a comfortable environment for people who have trouble with face-to-face interaction.

So the best thing to avoid your file being used for printing is simply to lower its quality and make it an unacceptable quality for printing.
You can export a PDF from your Corel Draw file and then use Adobe Acrobat Pro to change all the pages to image-only, and to a low screen quality (eg. 90ppi and less.) Even if your client has the idea of going to a print shop or using another designer to work on the files, everybody will tell him/her the same thing; your files are low resolutions 🙂
