Suppose I did fake a screenshot, and I supplied a source link. Anyone could click my link, read the real thing, and call me out on my bullshit. That’s the way it should be.

Encoding the source URL in the screenshot’s metadata is not bad. That would preserve the source credit in places where people simply copy your image and post it somewhere else. We’d have to make sure it’s not saving the full URL of a private conversation, where the full URL might leak a private key or a session ID. Can’t let someone turn on this feature and then accidentally doxx themselves.
