Nice. I wonder though, will the randomly placed watermarks distract the legit viewer, and affect their judgment of the images?
Example: When I go through Adobe stock photos, although I find the watermark initially annoying, I would quickly learn to "unsee" it in the next photos because I know how it looks like and where it is on the photo.
With varied watermarks, I'm not sure if the same mental technique can be applied. Shrugs, I may just be overthinking it.
