The problem is still the same. They trusted the client for what
concerns the bag itself. They should have checked all the stuff
contained in the bag and validate the "nodrop" attribute
server-side.

AO network system designer made a big mistake by using TCP. That was
the problem. Using an adapted implementation of UDP can save you
from this problem, as it's been already discussed on this list some
time ago. At the current state of the 'net, movement validation
isn't even an option. We've got to stick to current pre-emptive
algorithms to let the client do some calculation on the various
characters positions. We can't avoid this for now.
