That being said... here is my policy:
No modification to any of my photos is allowed. You may not remove
or alter my watermark in any way, shape or form. That includes
blurring, cropping, blacking out, blocking, watermarking over etc.
you want to post one of my photos from any of my social media sites, you must give me credit-"YLBB" or
"Your Lips But Better". Just using my picture with my watermark is not sufficient.
