A World of Warcraft WOTLK Classic Addon for Benediction players. Shows a message in raid/party and on your screen when you join with a blacklisted player.
Issue: When a player belonging to a blacklisted guild joins a raid group, the addon will emit duplicate blacklist messages for every subsequent player that joins the raid. Steps to reproduce:
Create a raid group
Invite a player from a blacklisted guild. Observe a message of the format "<'Guild Name'> is on the Classic Blacklist!" will be sent in raid chat by any users with the addon.
Invite another player from a non-blacklisted guild. Observe a duplicate message from the previous step is also sent in chat. This will be repeated for any number of players that are invited to the group.
In silent mode, it will instead print duplicate messages that only the addon user sees.
Workaround: Enable silent mode when this happens
Severity: High, having to enable silent mode defeats the point of the addon. Having the chat spammed with duplicate messages can be annoying for other raid members.
