The issue is that it is hitting a gitea instance and a mediawiki instance, then
getting lost in the commit/change diff system. I should just just figue out how
to dissable the difference tools on gitea and mediawiki to keep the bots from
going down a rabbit hole on a decade or more of commits and page edits.

These are CPU intensive which is my issue at the moment.

Get a small version of a very old very fast very inaccurate LLM.  Have it
generate a couple terabytes of endless nonsense.

Redirect scrapers to it, and poison whatever LLM they are trying to train.

I just had an issue with a web-server where I had to block a /18 of a
large scraper. I have some topics I could use some input on.

1. What tools or setups have people found most successful for dealing
with bots/scrapers that do not respect robots.txt for example?

2. What tools for response rate limiting deal with bots/scrapers that
cycle over a large variety of IPs with the exact same user agent?

3.  Has anyone written or found a tool to concentrate IP addresses
into networks for IPTABLES or NFT? (60% of IPs for network X in list
so add network X and remove individual IP entries.)
