My friend's dream is literally shattered and his life is completely going to get ruined.
He bought the writing service to do his final essay. However, the writing showed over 80% match on the Turnitin, and there is no way he can make an excuse for that. Now he has to go to a hearing panel for academic dishonesty and he will likely be receiving a failure for the whole course, and get a permanent note on the transcript for plagiarizing. He's only 2 semesters away from graduating with over 3.8 GPA. Don't make a mistake like him.
Who was the writer he went to?
Why didn't he double check it himself? It's not hard to google sentences or paragraphs to see if they pop up online. There are also plagiarism checking services and most writers who stay in business know how to beat something like turnitin.com
Your friend sounds like he got lazy and careless and now he's paying the price for it. If you're coming here to warn people about writing services in general, don't bother. If you want to warn people about a specific writer, that might be at least somewhat useful. There are plenty of writers who do a great job - just do your due diligence.
