There is some validity to this line of argument....however this happens all of the time around here whenever someone starts a challenge with "simple" in the title. People spend no time coming up with their own designs, they simply tweak other people's work by randomly removing a single rod until they get the same result. When they are successful, this mindless group gets recognized for having the "Simplest" solution, but the large majority of the credit should go to someone else.
And I disagree with your argument about brown rods. When you select a brown rod, the following message appears: "Solid wood rods (S): will collide with other solid wood rods". However, if you are careful and draw a second wooden rod on top of the first, then there is no collosion...and that set can even pass through wooden rods beneath them. That sure sounds like a glitch to me.
Bottom Line: It's just a game. The rules (including glitches) are part of the game. Lighten up and have some fun. If you don't want to play around with explosions and glitches, then don't. But don't waste your time trying to regulate what other people allow in their challenges or do with their designs.
