Two weeks ago Blizzard published a fix that would require players to be level 60 before they were eligible to post a group in the looking for group finder, in an attempt to reduce the amount of boosting spam experienced by players searching for a legit group.
The 9.1.5 Public Test Realm went live today, and with it came another new change to the looking for group finder.
Accounts will now require a Batle.net Authenticator before they are able to list a group with custom text in the group finder for Dungeons, Raids, and Rated PvP.
All players are still able to search and join groups, without an Authenticator.
World Of Warcraft Players Will Now Need An Authenticator Before Listing A Group With Custom Text
While the action of "boosting" is not a bannable action, Blizzard does not like players advertising these services in channels that disrupts other players, and this change should see a drastic reduction in spam, and those who continue will make themselves a target for a ban from Blizzard.
Blizzard has found that the accounts set up for advertising often were from compromised or throwaway accounts.
This is a welcome change for players as most people play with an authenticator anyway, and if they don't they probably should for security reasons, and it gives players an extra four bags slots.
This change is live on the 9.1.5 PTR and won't likely be pushed to the live servers for at least a month or two.
