It's a shame that the title of your thread paints all GVs with such a broad brush.
I'm not one to panic and get all wound up over something as petty as this, and such a problem like a graphics bug are solveable so it really needs just a bug report and not a slight against a whole group.
Curios about this particular comment, however:
No one should be "punished" for gleefully taking advantage where advantage can be found. But when that advantage is simply an exploitation of a design "bug" then it should be policed
This leads me to believe that you might find it acceptable to do, for fun, as long as it meets your criteria. What if someone else found it appalling that you would even do it "gleefully". Are they right and you are now subject to your own regulation? Who makes these decisions, and frankly, what on earth makes you think that we need a police state in there to Decide who is exploiting and who is being Gleeful? Who challenges that decision? Is there Glee Review Board that defines intent?
Do you honestly think that a simple bug report couldn't have sufficed and a slant against a group was really required?
Comments like this make me nervouse, how easily people succumb to requiring someone else to babysit and define "acceptable".
