Misleading people or putting a stumbling block before the blind is a serious matter. If a man or woman claims to be 'free' and they turn out to be married, they have caused someone to commit adultery. They could also leave some man with another man's baby, and this could unknowingly lead to incest when that baby grows up. To say people on the internet are all liars doesn't mean it is correct or acceptable. There should be standards of truth in 'advertising' services!
