[2022] Ty blizz for the policy update

Organizations who disruptively advertise across all realms and establish escrow services are the primary target of this policy update. Guilds and individuals who are inviting players from another realm to join them in traditional game activities in exchange for gold are allowed, as they were before.

That depends on the definition of “financially”. If it means an exchange of gold only without a middleman entity, then it sounds like the same sort of guild activities players have been enjoying for 17 years, which are not the focus of this policy update.
