Captcha-style distortion of sensitive keywords and symbols in the images seems to work quite well but I'm getting censored/flagged on FB, with some of the black box cornered ones. Also tried splitting the images into sections to maintain legibility.
Twatter just shadowbans or bans. Fakebook does that stupid banner over top of your image, so it's really easy to tell if you're censored. Getting many reactions on twatter???
