I wouldn't be surprised if many more people used this "green arrow" cheat, but kept quiet about it. It's really easy to do, there are even instructions indirectly showing how to do it on cRPG forums. Back when Pandor was first banned for green arrows, rules weren't clear about it, but he opened admins' eyes on "texture hacks" like these. To be honest, if you shoot an arrow, it becomes practically invisible after a few meters, and so you have no way of telling how much they drop and how high you should aim, the only hint is the hitmarker sound if you hit someone. So I can understand why someone would want to swap the current, almost invisible arrow model with something like green arrows or roast chicken. Green arrows are there not so you can dodge better, but so you can actually see where you shoot. Other than that, Pandor said that he doesn't use green arrows anymore, so he's no longer a cheater.
