Let's have a fast economics lesson -
Your post refers to as what society calls "socialism" (common wealth controlled and distributed by the community) this is good on paper, except that everyone will be the same; therefore reducing drive and overall general pool of wealth.
Now in this sense, I'd like to introduce "capitalism" (trade and wealth are controlled by private entities; in this case the user/player) - therefore increasing motivation to make "money" and a economic standing.
By promoting your "farming" methods more players can do that and it ruins your trade. If "X" restaurant reveals their secret ingredient to others, then what is the point of going to that restaurant? You can go down the street potentially saving money and time.
Where I'm going with this (tl;dr) is you should find a method that works best for you and keep it to you as it reduces the amount of players doing the same thing (this is a public forum after all) and increases your profits by reducing flooding and saturation. Not to mention the less people doing it, the less likely blizzard is going to catch on to it.
