Midjourney terms state that paying members own the created works and can be used with out attribution. Posting such would clearly not be fraud. Should it be rewarded... in a vacuum I don't think so; but there is going to need to be a little more nuance. If I were to build a logo for a project with licensed AI or pay to have one designed it would soon become a trademark in practice and no attribution would be necessary in either case.

AI is going to continue driving the cost of things lower and lower. This is a good thing because we will all have to work less and less. I hope hivewatchers can balance AI reward farming with AI as a productivity tool(grammerly, just typing in japanese...). It's not going away.
