Why does Harold Camping of Family Radio continue to lead people by the nose ....?

My understanding of the scripture is that ... when it says that a day in the eyes of God is as 1000 years to man ---- it just refers to the eternal nature of God .... so days would really be immeasurable. This is not a definite timeline --- it could jast as easily been spoken of as 5000 years or 10000 years ..... Why does Camping continue to lead people astray ? Does it really increase his wealth ? Does he not know that any legitimate understanding he may have is negated by his erronious and callous calculations ?
