we scrub metadata from images uploaded to hexbear

Now that the thread quietened down, I did want to comment on image sharing as well. We already know that Facebook implements tracking in metadata, but there is a concern that they might resort to advanced steganography to link images shared on other sites to their origins. If you're familiar with unsee(.)cc, they implement this by just straight up plastering your IP over the image, but this could be taken further by encoding dots or some wave pattern. Combatting this is really difficult, and I don't expect us to be able to do much. Personally I've been applying a slight imperceptible distortion to images which I shared from somewhere I expect to get tracked on, but that's extremely overkill. Just wanted to share, since I doubt I'll get another outlet.
