It's honestly difficult to avoid. At its best, AI generation is used as a starting point by artists who know how to improve on the result to make it their own, and in these cases the fact that AI generation was used might only be evident in how fast the artist in question is able to produce their pieces.

As for the issue of training data and how licensing should work around acquiring the datasets used to train the models, that's a discussion that the community really isn't for. Suffice to say, I think these models are standing upon the shoulders of artists past, and that should be taken into consideration in their creation and use, in way that currently isn't happening.

I'll enact rules if someone starts spamming posts of straight unedited output, but until then I don't mind posting the occasional curated piece that is a cut above the rest of the flood.
