The policy update was shared by community manager Kaivax. “As of today,” it says, “we will now prohibit organizations who offer boosting, matchmaking, escrow, or other nontraditional services, including those offered for gold. World of Warcraft accounts found to be in violation of this policy are subject to account actions”. With the policy change, all organizations and members doing business of this nature have been asked to stop, but there will be potential penalties if they don’t. These might include sanctions all the way up to bans.
With rumors going around that boosting communities might be banned, there were some community members arguing against it, saying that banning RMT transactions would make sense, but banning services that players provide and are paid in gold for, would be going beyond what is necessary. Some suggest that banning these kinds of transactions for gold doesn’t make sense because it might encourage more RMT action. However, Blizzard has decided to remove boosting services regardless of how people pay for the advantages. Rolling all types together is likely a simpler way than trying to separate out the payment method.
One clarification is that the policy update doesn’t prohibit trade channel communication or selling in game items or activities for gold but boosting communities, especially those with operations across servers, are now specifically banned.
