    Really great piece. We have recently seen many popular lemmy instances struggle under recent scraping waves, and that is hardly the first time its happened. I have some firsthand experience with the second part of this article that talks about AI-generated bug reports/vulnerabilities for open source projects.

    I help maintain a python library and got a bug report a couple weeks back of a user getting a type-checking issue and a bit of additional information. It didn’t strictly follow the bug report template we use, but it was well organized enough, so I spent some time digging into it and came up with no way to reproduce this at all. Thankfully, the lead maintainer was able to spot the report for what it was and just closed it and saved me from further efforts to diagnose the issue (after an hour or two were burned already).

        The theory that the lead maintainer had (he is an actual software developer, I just dabble), is that it might be a type of reinforcement learning:

        • Get your LLM to create what it thinks are valid bug reports/issues
        • Monitor the outcome of those issues (closed immediately, discussion, eventual pull request)
        • Use those outcomes to assign how “good” or “bad” that generated issue was
        • Use that scoring as a way to feed back into the model to influence it to create more “good” issues

        If this is what’s happening, then it’s essentially offloading your LLM’s reinforcement learning scoring to open source maintainers.

      AI scrapers are a massive issue for Lemmy instances. I’m gonna try some things in this article because there are enough of them identifying themselves with user agents that I didn’t even think of the ones lying about it.

      I guess a bonus (?) is that with 1000 Lemmy instances, the bots get the Lemmy content 1000 times so our input has 1000 times the weighting of reddit.
