It bothers me as well. As someone who went to school for art and design I’ve been trained to be a snob about things like this. I’m sorry. I appreciate people posting photos. And your photos are really great. But I see the watermarks immediately. Fine, sure no big deal I haven’t said anything and I click like to show my appreciation. But it’s getting to the point where I am not wanting to click like because I don’t want to encourage it. It’s just messy and visually offensive at a certain point. So I think the above critiques are valid.
I still enjoy your contributions and don’t want to sound like a jerk.
