What if you kill someone later on because of gaps in your knowledge caused because you didn't do the study required?
This self proclaimed "notable" author claims to be a writer of import but fails to establish any writing credibility in any of his social media and employment link profiles. He is just like all other writers here, a ghost writer trying to earn a living by writing for other people. So do not believe his claims of being on the level. His ire was probably directed at students who refused to hire him for overpricing or something.
By the way, no student who uses writing services can end up killing someone in the future. If he isn't studying, he is eventually going to fail his course, regardless of the papers written for him. He is not going to pass his tests, which carry more weight than any research paper grade that is written for him. Nobody passes a class based on essays alone. If anyone has passed college classes based on research and essay submissions alone, please tell us how you did it. I am sure everyone here would be interested to learn how it is done. Right?
