As a Dutch speaker, I can confirm that those translations are pure and utter crap.
The sentence structure is just plain bad, I even think Google Translate would do a better job than this.
Which projects has he cheated? Might be worth contacting them so they can remove those translations.
If I saw a website or service with that sort of Dutch, I'd distrust them immediately.
He is just starting his career. I have warned most of the projects for which he has been 'translating'. I'm also warning projects to which he still sends applications, almost daily. A more steady solution would be if a DT member would tag him. It's not really a hobby of mine to check his applications on a daily base and keep warning projects.
