Hey guys, a question for my fellow commission cartographers out there.
Do any of you guys use a copyright license agreement or similar? I usually charge different prices for different types of use, but I imagine it'd be really easy for a client to say his order belongs to the cheapest category (strictly private use) and still use the image for other purposes afterwards. I don't feel like using ugly watermarks and I don't even want to start this dangerous game of mistrusting my clients, but I also don't like to be cheated/robbed.
So I guess my question is: how do you guys make sure your maps aren't used for things the customer didn't pay for?
