At least creators of Open Game Art don't have A.I. algorithm scripts to report to some lawyers to sue users like me.Judge verdict could be money penalty.All what admins and moderators can do for now id too ban some user temporarily or permanently if some user keep breaking rules despite warnings you just letting know that uploading some character models from abandonware aka freeware pc games and you are then you are just deleting such a character models to avoid dmca threats in future.
