Any material that I have shot and therefore own the copyright to, has a watermark along the bottom or side, so as not to be intrusive.
The only time my material is seen without tghis, is when an affiliate who I know to be trustworthy needs it without. They do have to inform me of all the URL's the images re used on, so that if I find any posted on forums etc. I know where they came from.
Shoots cost $250+ for solo/toys, so why should I let people use it without acknowledgement. This is also part of UK/EU copyright law. A photographer can insist on credit being given for his work where ever it's published
