I don't really see anything wrong with selling runs as long as everything is on the up-and-up (clear rules laid down, everyone is treated respectfully, etc). It's just something to do to raise money for a guild, and it can help get people access to things who might otherwise never get it. Selling achievement, mount, or boss clears was a common thing in my time in WoW, and I never batted an eye. Things become not-okay when someone decides to sabotage other groups to stir up demand for their for-sale runs.
