I think you might have misunderstood.

Poserworld has been around for over 9 years now, and they wouldn't still be in business if they took that stance.  Lots of people have been members at one time and no longer a member at this time, and they are still allowed to use the content they downloaded while a member.

Some people become a member for a while. Take a break and then join again months later when there is more new content added.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
