Advice for freelancers

There is a employer named Stuart 1971. He is extremely rude when he posts projects and almost threatens the freelancers he hires. I took on his project nonetheless and completed it. He then posted all sorts of abusive language on my profile, out of nowhere. He also sent me a threatening email saying that he would post rubbish on my profile. The language he has posted on my profile is very objectionable. He has also made his profile inaccessible to others. My advice would be to stay away from this person, even though he pays well. He will torment you and take away your peace of mind. What he has written on my profile has got my family and me really [login to view URL] away from him. I have seen other freelancers complain about this person also.
