The fake or low quality projects are an old thing now, the worst thing i have seen is the trend of the meme and nft based projects, I mean if you have something valuable or worthwhile to sell that is great but i have seen people selling senseless pictures amd even selfies as nfts and collectibles, this trend should stop atleast untill there is a serious purpose added to it at the moment it is a joke.
If there is demand then it will continue the market thrives on demand and supply, the developer and the creator will supply as long as there is a demand for the projects I have seen what you are talking about, and the market has a potential because these a marketplace for artist and we have a lot of artist in our community, so let's see how it will go in the future.
