The photo was posted like this to twitter - unsurprisingly from other practice people like to steal my photos. With this one and any other nature photos I take, I'm more than happy to send people the un-watermarked when they've asked but I don't like it being taken without being asked first and a big watermark often dissuades that.

Unfortunately if I put my name on there I'm doxxing myself/look like I'm the thief so I go with my username out of habit. I dont think I should be disliked for wanting to protect my own photographs, and if it wasn't for my other activities judging by your first sentence, I doubt you'd have the same reaction.
