I agree. I like Lobsters but the political brigading is unfortunate and the moderation seems to favor one side over the other. That almost sours the whole experience, but I've learned to hide low quality drama posts and move on.
Having participated in both sites for over a decade, I disagree.
Lobste.rs was pitched as having more open moderation with a public moderation log, but in practice it's mostly one moderator running the show and deleting comments they don't like. There have been some notable incidents over the years where relatively benign comments were used as justification to ban people, the original comments deleted, and then the moderators come in to provide an alternate story of what happened. If you step out of line and question that narrative, you could find yourself silenced as well. Long term users know how and where to toe the line, as well as which topics to avoid completely unless you want to get that famous pop-up that shames you for having your comments downvoted and ends with an invitation to delete your account.
The moderators on Lobste.rs also weave their narrative into the fabric of the site in unavoidable ways. For example, you can't post anything related to LLMs without tagging it "vibecoding". Most of the articles are not about vibecoding, but they've decided that everything related to LLMs is "vibecoding" and therefore that tag is your only option. Don't think you can tag those stories as "AI" because that's wrong and they'll change it to "vibecoding". It's a silly decision that users have been carefully complaining about for a long time but the message from on top is that LLMs are to be sneered at as "vibecoding" and therefore that's the only permissible narrative. You don't see anything like that coming out of HN, for all it's imperfections.
