Also: reddit pinky promises to implement mod tools they've been pinky promising for more than 5 years. Back when overwatch 1 came out, I became a mod for /r/overwatch_memes (now dead, the subreddit without an underscore ultimately was better) and even modding this subset of a subset of a gaming community would have been impossible without the API. Several moderation features that I ended up developing a bot for (using the API), reddit had been promising to implement for some time, and none of them are currently implemented. If you've been a mod all this time, you know that reddit promises to mods are completely empty. It's been fine until now because you could rely on other tools but modding anything with regular users without these tools is impossible without significantly restricting rules on allowed content.
I think there's still a remote opportunity they claw trust back, but it's getting smaller the longer they have their CEO out there telling people to get stuffed.
• AssistantBOT, AssistantBOT1 - This was broken by the Pushshift API cutoff. It's widely used for tracking sub usage statistics. The author is working on fixing it, but the last update was three weeks ago.
• Flair_Helper (Blank-Cheque) - This makes removing posts easier, especially on mobile. I haven't used it in anger.
• FloodgatesBot (Blank-Cheque) - This applies posting limits for users. There are a couple competitors, but I'm not sure how many are still running.
• Quality_Vote (Blank-Cheque) - This is used to allow users to remove unpopular posts. It can save a lot of moderation work in the right kind of sub.
According to the linked article, even the bots which exceed the usage were manually whitelisted to stay free.
