This is not behoimi (which is most likely the place where you got this). Lalaca knows far more about what is welcome on here than you b4d0m3n since you apparently do not get the message from your deleted posts.
Until you mentioned it, I was not even aware of behoimi. Is Lalaca the owner of this particular site? Are you? If the pics are unwelcome, they will not get moderator approval. That's all there is to it. If cosplay pics didn't exist on danbooru I would give more than two shits about what you have to say, RiderFan. ;) Thanks.
