The individual instance policy doesn't matter because anyone can spin up a Lemmy instance and get the data via federation bypassing any antibot crawling or instance policy.

A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, toxicity and dog-whistling are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !uspolitics@lemmy.world
7) No Hit-and-Run questions.
Please don't delete your post for no apparent reason. If you plan on deleting a question later, say so in the post, or if you feel that you have a good reason to remove it, message a mod beforehand. It's not fair to the ones who took their time to answer, and it's not in the spirit of the community.
8) No Bots.
Posts or comments from bots, LLM's, AIs, Neural Networks, Transformers, or Marvin the Paranoid Android are not welcome in AskLemmy. Real humans only please.
Reminder: The terms of service apply here too.

There are already instances doing this (and Mastodon ones as well), it's a thing - there are warehousing no-user instances[1] But they could be blocked! We can't have that, luckily...
...the Lemmy API and RSS feeds have no authorization around them for consuming the firehose of data; if I were a person doing this data gathering, I'd just passively monitor the firehoses off the top instances from random rotating IPs. Could and is most likely happening right now, can't block them.
[1] I personally wrote a simple script which uses the fediverse observer info, grabs the XX most popular communities and builds a subscription import file to bootstrap a new Lemmy instance. wasn't hard, just some curl and jq work.
Dang, I suspected that might be the case.
A bot scraping the fediverse would be indistinguishable from any other kind of federation, only the purpose differs.
I don't know how true that actually is: sh.itjust.works just blocked like 3 networks they detected doing AI scraping.
Bots scraping the website cause high levels of server load because compiling a page is an intensive activity, and so instance admins are taking active steps to stop this in order to stop all the scrapers bringing down the server.
But if they actually wanted Lemmy content (as opposed to the bots scraping everything on the internet they can find, and happening across Lemmy) then they can just start an instance and have other instances send them the content via normal federation. It would be almost impossible to tell this from a normal instance, and would be more efficient for everyone involved.
Well don't give them any ideas lol
As someone else already mentioned, it's almost certainly already happening. Lemmy federates with Mastodon, and Mastodon has a user base and a volume of content that would be hard to ignore. So there are likely many Mastodon instances that are slurping up content from Mastodon, Lemmy, Piefed, Pixelfed, anything else across the Fediverse, and using this to train AI.
It would just be nice if they didn't crash servers doing it.
the instance's stance matters very little, for a lot of reasons:
- nobody hosting a lemmy instance has the resources or interest to do ai training,
- there isn't enough on lemmy alone to constitute a useful dataset,
- nothing on lemmy is encrypted, save user credentials; every post and message you've ever sent is completely public. there's no way to make it harder to scrape without modifying the software, and even if you went that far,
- in order for federation to work, everyone must be able to read everything. everything you post literally gets copied to other instances so they can see what you wrote.
the only way to be sure that nobody is using your instance to train ai is to run your own instance on a private network with federation turned off.
is to run your own instance on a private network with federation turned off.
But I like talking to myself!
sh.itjust.works
Thanks!
I don't think it's a case of "allowing" ai crawlers to scrape data.
The AI data crawlers scrape everything, it's a matter of stopping them, not if they allow it explicitly. And these companies have found other ways around larger players that have tried to stop them.
Might as well take a stand against the weather.
you should just leave the internet, you'll be happier, AI isn't going anywhere anytime soon
While I suspect you are correct in your assumption about ai, there are better ways to convey this than telling someone to leave the Internet .
Don't argue with sloppers. Just downvote, block, and move on.
