We have put together a short summary to try to assist people in what to avoid on forums or web sites as we have received comments recently from people using Chinese sites saying they didn't know the charts are illegal copies. It is a non-exhaustive pointer guide. The countries specified are examples as obviously not all sites from these countries are violating copyrights but unfortunately the worst sites are found on their servers & takedown requests are often totally ignored.
Mainly it is common sense but sometimes it can be hard to tell which is
why we recommend anyone in doubt to ask either a designer, a specialized
forum or the Association.
This is a basis for educating and debate on the subject, as most of our posts are.
