The developers at Pearl Abyss know about the mod, but there has always been a quid pro quo, relationship with it. As long as it did not interfere with gameplay, and people kept it to themselves they tolerated it. The second idiots start posting it to the beauty album, or official game forums, in a way that makes it a problem, is when they will ban it. Post your nudes here, or on discord, keep it off BDO's radar. Low key.
