Is there a userscript to subtly change the hash of images I upload on 4chan, to prevent people stalking me through archives?

Uploading an image to 4chan does change its checksum, and changes it's binary content quite radically. I don't know if that's just due to compression, or if a digital watermark is added. If the latter is true, then someone who knew the algorithm could track you.

No.
>or if a digital watermark is added
Ironically, it's because it strips metadata that could be used to track you.

If you download an image from an archive or from 4chan and post it again, it will not be altered.

False. An image I posted earlier today contained no metadata, but got modified. Q.E.D.

>If you download an image from an archive or from 4chan and post it again, it will not be altered.
True. I posted pepe.png above to see if that was the case. Q.E.D.

All that would prove is that one *or more* people posted the same image. Unless you use a tripcode?

The filename is a bigger anonymity problem than the image itself. But you can change it easily.

Use an image you got from a different board, or post that image to a different board. Obviously don't post anything anywhere inappropriate.

Isn't that a feature in 4chanx? Mobile apps like Kuroba and KurobaEX have such a feature. (I know because all I do is phone post.)
