That can still be exploited so i dont see that happening. We should just wait as karyuu said and see what the devs do to fix this problem.
The fact that one proposed solution (albeit possibly terminally flawed in itself) to a possible systemic problem (as opposed to the more regular variety of bug) can be exploited, does not mean that all thinking should stop there.
A more productive way would be to look at what a proposed solution aims to address. It may very well be a starting point or a possible angle of attack on a problem that may occur in future.
Having a wishlist, methinks, is the kind of thing where input is invited. Even the most uninformed input can sometimes spark a new line of though in someone who has the knowledge and skill.
So instead of saying..... Can be exploited.... kill it, try the following:
a) What does the suggestion aim to address or improve
b) Could this become an issue or systemic problem in future.
c) If the current way of thinking may lead to such a problem then:
d) What kind of solution would best suit the problem.
e) What are the real inplications of particular solutions. (eg... what IS the exploit)
f) Can possible exploits be avoided in developing a solution.
At this point healthy debate can start.
