Why?
i forgot the name of the site but this manga is copyrighted. plus unlike raws that get translated by groups this manga has an official english version that is pay to read.
so if the person that uploaded this gets found out it will lead to legal issues.
that also being said, since this site don't show who uploaded what they will be harder to track.
Your right about that Its really good that person didnt leave any trace of being uploader. He unknown to us that really awesome(╯°Д °)╯╧╧
ok the person who uploaded this took a huge risk by doing so
