You probably know about those imaginary art subreddits, where you can share art with specific theme (e.g., ImaginaryMonsters where you can share artwork with...imaginary monsters, yes) and there is a bunch of these. I was thinking of making one community that I would call something like ImaginaryAnything where people could share art with any theme, and just mention the theme in the title, instead of having 100s of communities for each specific one, since lemmy is pretty small still. There already are some specific imaginary communities on lemmy but non of them are really active.

My main concern is copyright issues, would there be any? I wouldn't want to cause the instance admin any problems. Every post would be required to credit the author and to link the source, but could images hosted on the instance cause problems? In case they could, would linking the source image link instead of uploading it to the instance avoid such problem?
