Those protesters who get doxxed by 4chan, didn't take their privacy seriously enough. They are constantly at protests, wearing the same clothes and around the same people and all have easily identifiable radical beliefs that stick out like a sore thumb. Having one picture of yourself, where most of your body is covered up, wearing a t-shirt and workout shorts isn't going to get doxxed. Cover your face, cover any birthmarks or tattoo with tape. Take the picture in front of a blank wall. Stip out exif data, upload to dropbox with a passworded link, send it to mod. No one, 4chan or otherwise will be able to doxx you. Not saying that you need to get verified. I don't particularly care if you do or not. But there are ways to do it without risking yourself to exposure.
