A: To better understand why gold buying is wrong, please read this article. Although the article is from another company, it is the same across the MMORPG industry. Have you ever known someone who's account was hacked with their gold or items stolen? Often times the gold you are purchasing is coming from their stolen account. Buying their gold also encourages the gold sellers to spam the community, which disrupts everyone's game play. Please have respect for your fellow players and the community by following out ToS and not buying gold.
