What I do is to run the exiftool to strip all the metadata from the image. Next, I check if there are any identifying details in the image like landmarks or background details (e.g. stuff on my whiteboard). And finally I check for the unwanted reflections or for the setup that could be recognised outside the community I share the photo with. Last but not least, I never share a photo in more than one place.
I’m not too fussed about those things tbh. If anyone really wanted to doxx me on here they could do that regardless of any images.
I wouldn’t post any pictures of myself to publicly available websites, though; even the one I use on facebook is years old.
