This is to be expected. CMC means business, they don't need to regulate the project who wants to be advertised. It is our responsibility to investigate if the project is worth to invest and worthy of our time.
CMC is just being used to put up their banner on its website to become known that a certain project is actually started running. CMC doesn't mean anything to them but as a tool.
CMC are listing projects that pass in their requirements, they will put the exchange where its listed, their ANN thread, and their social media channels.
That's it, its pretty simple as they don't want to make things complicated, if they will have to investigate, I think it would take a lot of time before a single coin will be able to be listed in CMC.
read this, its important,
