If you can't say something nice, don't say nothing at all. I like to share my photos of landscapes and night skies on social media, but I do not like when some people copy others' photos without permission or taking credit for someone else's photo, I have only experienced that someone has tried to take credit for my photos and I do not like it! otherwise I have also experienced that someone has shared one of my photos. All photos and videos are taken by me, do NOT copy my photos and videos without my permisson. Don't even try and take credit for my photos or videos.
