I wonder if you could mess with AI input scrapers by adding fake captions to each image? I imagine something like: (big green blob) "My cat playing with his new catnip ball". (blue mess of an image) "Robins nesting"

A well-written scraper would check the image against a CLIP model or other captioning model to see if the text there actually agrees with the image contents.

Then captions that are somewhat believable? "Abstract digital art piece by F. U. Botts resembling wide landscapes in vibrant colors"

They do have a robots.txt [1] that disallows robot access to the spigot tree (as expected), but removing the /spigot/ part from the URL seems to still lead to Spigot. [2] The /~auj namespace is not disallowed in robots.txt, so even well-intentioned crawlers, if they somehow end up there, can get stuck in the infinite page zoo. That's not very nice.

Given that current LLMs do not consistently output total garbage, and can be used as judges in a fairly efficient way, I highly doubt this could even in theory have any impact on the capabilities of future models. Once (a) models are capable enough to distinguish between semi-plausible garbage and possibly relevant text and (b) companies are aware of the problem, I do not think data poisoning will be an issue at all.

There's no evidence that the current global DDoS is related to AI.

The linked page claims that most identified crawlers are related to scraping for training data of LLMs, which seems likely.

Love the effort. That said, these seem to be heavily biased towards displaying green, so one “sanity” check would be if your bot is suddenly scraping thousands of green images, something might be up.

Nature photographers around the world rejoice as their content becomes safe from scraping.

> compression tends to increase the entropy of a bit stream. Does it? Encryption increases entropy, but not sure about compression.

I can see what was meant with that statement. I do think compression increases Shannon entropy by virtue of it removing repeating patterns of data - Shannon entropy per byte of compressed data increases since it’s now more “random” - all the non-random patterns have been compressed out. Total information entropy - no. The amount of information conveyed remains the same.

Technically with lossy compression, the amount of information conveyed will likely change. It could even increase the amount of information of the decompressed image, for instance if you compress a cartoon with simple lines and colors, a lossy algorithm might introduce artifacts that appear as noise.

Next we do it with red and blue :D

We have investigated nobody and found no evidence of malpractice!

Reading about Spigot made me remember https://www.projecthoneypot.org/ I was very excited 20 years ago, every time I got emails from them that the scripts and donated MX records on my website had helped catching a harvester > Regardless of how the rest of your day goes, here's something to be happy about -- today one of your donated MXs helped to identify a previously unknown email harvester (IP: 172.180.164.102).

This is very neat. Honeypot scripts are fairly outdated though (and you can’t modify them according to ToS). The Python one only supports CGI and Zope out of the box, though I think you can make a wrapper to make it work with WSGI apps as well.

Faking a JPEG is not only less CPU intensive than making one properly, but by doing os you are fuzzing whatever malware is on the other end; if it is decoding the JPEG and isn't robust, it may well crash.
