If you have issue with carvings used by the Brigands, I advise you leave the faction that is causing this. If you're SD, you'll get hit, if you're a knight, you'll get hit. The carvings hit our guild's enemies, not each individuals enemies.
To avoid these carvings, all you have to do is leave the organization that holds enemy status to the brigands.
