This site has no paid content, so I was surprised to receive an invitation to advertise an essay-writing service for some undisclosed bur probably insubstantial fee. Guardian today highlights the latest euphemism, a "proof-reading" service for students, mostly foreign students, whose English is not good enough for them to write their own essays and complete their courses. This is a racket that should be shut down at once, and another indication that coursework has become corrupted to an extent that invalidates it.
