Wouldn't the core issue fall on the team for not being specific in their rules? it's common sense that if they want to launch a brand, they wouldn't want a logo based off of another company or even anything close, but this is bitcointalk. I've found that you have to freaking map out everything to make sure even the most ignorant would understand.
True but a professional logo designer would never go with such copy paste job as he knows logo means what to a company as you said and I stated earlier that it's common sense.
I see a lot of people are trying to defend themselves here with a lot of excuses. Come on, man. You don't need to. If you are a professional logo designer, why would you even bother to use other people's work in a brand logo?
