After some bad experiences in my career in World of Warcraft, I decided to provide an addon based on another addon.
With the add-on it is possible to block the spam in the trade chat or in other chat channels so that you can talk quietly in the chat again.
Everything that is in the filter can be blocked.
At the moment, only boosters and the annoying Twitch streamers are blocked, as these advertise dubious offers the most
This addon is available for TBC as well as for Retail and should work without any major problems.
Some parts are taken from the BadBoy addon with permission from its author Funkeh
Unfortunately, some are of the opinion that the ToS do not apply to these people, so new updates are coming again. And if something does leak out, please let me know so I can fix it.
Blizzard has now issued a ban on booster communities.
