I hate it...
using the google image finder one can find tons of watermarked images....
I hate it because many sites that use watermarked images are in hyroglyphic (non-arabic) fonts like Korean or Greek, have no contact adress, and if they have something like this they do not provide any document of correct image licensing, if one asks for.
What I hate the most: even if you use a DMCA Takedown Request nothing happens. NOTHING!
It seems to me that beeing a copyright owner is less worth than nothing!
