Hello Lemmings!

I am thinking of making a community moderation bot for Lemmy. This new bot will have faster response times with the help of Lemmy webhooks, an amazing plugin for Lemmy instances by @RikudouSage@lemmings.world to add webhook support. With this, there is no need to frequently call the API at a fixed interval to fetch new data. Any new data will be sent via the webhook directly to the bot backend. This allows for actions within seconds, thus making it an effective auto moderation tool.

I have a few features I thought of doing:

  • Welcome messages
  • Auto commenting on new posts
  • Scheduled posts
  • Punish content authors or remove content via word blacklist/regex
  • Ban members of communities by their usernames/bios via word blacklist or regex
  • Auto community lockdown during spam

What other features do you think are possible? Please let me know. Any questions are also welcome. Community requested features:

  • Strike system

Strikes are added to a certain member of the community and the member will be temporarily banned within a time period if their strike count reaches a certain threshold

  • Post creation restriction by account age

If an account’s age is lower than X, remove the post.

    I think the strike system would make sense and limiting by account age might work as well, but I don’t think the other simple methods of moderation are going to be that useful, as word blacklists always have false positives and auto community lockdown could be exploited by someone to sabotage a community. (like with a denial of service attack)

    Also, this is just my opinion but I really hate it when software speaks to me like they’re real people, I understand that it is ultimately written by a person but when the same phrase is repeated to every person regardless of the context it just annoys me. Similiarly I don’t like the automod messages/comments on reddit because it just feels like low effort content in comparison to what real people post on there.

    I think this would make more sense framed as a plugin rather than a bot, because a bot post is placed equally to a human post while being inherently lower importance.

    If I were to suggest features it would be something like a large language model based content filter, but I understand the computational and cost limitations would make that challenging.

      LLMs are too expensive to run and slow as well. As for the lockdown system, DoS as in sending API calls to send messages? Yeah well that’s considered spam and will indeed lock the community down. But it won’t happen instantly and I still need to plan how it would detect spam and whether it will attempt to automatically ban the spammers or not. The bot is still in the preparation phase, I haven’t done any work yet.

      As discussed in some other comment, the bot will not delete posts that are triggered by regex or word blacklist but report them. The bot indeed won’t understand context so it will do more harm than good. I am also thinking of transliterating content to catch people using symbols that look like certain characters like € for E and $ for S. That will be done at the webhook level though.
