The same thing can be said about Flickr. I am an active user of that site and use it to host most of my images that I post here. I'm guilty of not always commenting on photos that I favorite either, but have been trying to make a better effort to do so.
With both sites, there is the possibility to claim an image as your own. I really do want to prevent that with images that I would be upset over someone doing so. Earlier today, you may have noticed watermarks on some of my photos. I decided that the images I post (that are mine, of course) that I do not want stolen will have a watermark from now on. I will be placing it on the image in a way to not deter too much from what I am sharing, but it will be over the subject so that someone couldn't just crop out my name.
I also am going to follow suit with the ladies over at Clover and Violet and publically proclaim that my blog is Pinterest friendly. I will be placing the button that Jennie and Clara created over on the side. I do ask the following things however:
1. Please do not pin any personal photographs from my blog. This includes the photos I post of myself, my boyfriend, or my dogs.
2. I would love it if you would leave a comment letting me know you're pinning something of mine! I don't necessarily need to grant permission every time, so a comment would be great.
3. Link each image back to its proper post.
Until the day comes where everyone is honest and respectful, this is my way of protecting myself and my creative output. I hope you understand and have a great day!
