I would approach it as you described and be open to requests from creators to remove content as those situations arise. You’ve done more than your due diligence and have made it clear that you intend to attribute credit to the creators

I can’t speak for all the other refugees standing on your doorstep, but I’m just thankful to have somewhere to be. This kind of transparency is refreshing, and kind of makes me glad something went wrong so that the impression is made. Thanks 🙏
