Postmill VS notabug

I have not tried this one, but Postmill [1] is similar to HN and phpBB [2] is an off the shelf forum platform with incredible moderator capabilities but I think an add-on is required for voting.

Another one like that I saw recently was Postmill [1a][1b] but I have not tried it.

It doesn't support ActivityPub indeed. Somebody else has to put in that support in Postmill (the link aggregator software powering Raddle), and the developer herself is not interested in implementing that support herself.

It does! The source code seems like gnu-esque licence.

Postmill is sort of an old.reddit clone you may be able to bend to do your bidding.

I was on a reddit clone for a while for a banned subreddit for my favourite comedy podcast (to remain nameless, but after a while it got racist and I had to leave). They used https://gitlab.com/postmill/Postmill and it worked fine. It's open source so they could modify it a bit (saving posts, bots etc). The main issue was that over time fewer and fewer people came to the site, leaving only the most extreme and toxic people.. The nice thing about reddit is that it provides a fairly constant inflow of people.

What are you looking for, php engines? They are, some are written, examples: https://gitlab.com/postmill/Postmill. I am doing Agouti myself, but it is only being developed, it in php, but this is more for now an educational project agouti demo, etc.

A free and open-source P2P link aggregator with a strong resemblance to old.reddit.com

I did a quick search through Notabug's source and I think I found something. There is /packages/indexer/src/sorts.ts and /packages/peer/src/Listing/ListingSort.ts. I think the first file is what we're looking for here, but I can't be sure since I'm not fluent in typescript and there's not much documentation.
