The spammer has really gone to town here:
- There's random speckling all over the images to upset hashing and OCR techniques
- There's no URL in the message itself (it's in the image)
- The entire image has been rotated to the left to obscure the text
And, of course, they are not going to be content with just one rotation and can randomize the angle per message:
And they've gone even further by slicing the image up, randomizing the angle and overlaying the elements using animation.
