I'm not actively removing submissions that utilize AI art, but I do prefer that it is avoided when possible. Technically the wording does say "do not use AI in any part of your submission," but I'm focusing on music for the most part with that. Not everything is easily enforceable in that context either; more or less, we just try to follow the honor system - this is a competition about skill, fundamentally, so shortcuts really only prevent your own personal development in the context of using AI to do things like postprocessing.
I understand that time is limited, but I find the best way to get votes is to just vote on other peoples' entries as well, which is ultimately also a great part of development.
