The thing with this watermark is (and that's the reason why so few artists use it in the first place) that it ruins the picture. It's so intrusive and in your face that you just can't enjoy a picture anymore.And in some way, the art thieves win with this watermark because of that, just in a different way. It's like "If we can't steal this picture because the artist prevents us from doing that, then we destroy it by forcing him into using a watermark that ruins his picture!".How about you would make a costum watermark for it that works similar, but is less intrusive and detrimental to the picture and protects it in the same way? I mean, like WhiteDreams did it here:Just not all over the picture, but smaller and more in the corner, at a spot where it does no harm to the picture. I have no clue how she's making these watermarks, but maybe you could ask her for it.
