I think I have a pretty good example to highlight Blockland's uniquely stuff management. There was a game called Cortex Command, 2D combat game, it was included in one the early Humble Bundles, I think either 2 or 3. I fell in love with the game and logged like, 300 hours into it. The game was the alpha of alphas, there was barely any content for it - this term gets thrown around a lot, but it really did feel like a tech demo. It wasn't a particularly good game either, its main selling point was having every pixel simulated, think Noita, and also some beautiful pixel art. But nonetheless, it had a thriving mod scene, insanely thriving considering how small and feeble the game was, due to it being easy to code and having developer support. Anyways, the game gets a couple updates, they add an official "campaign" that was just retooled skirmishes, but no content. Developer radio silence for years, eventually the developers add an update to the game's menu that advertises their new game. The mod community eventually moves on, the game dies, so it goes.
So, we got an indie game with a good selling point and foundation, but not much content, that garners a loyal fanbase, who begin to mod the game and populate it with free quality content. The game is watched over by disinterested devs who don't impede the modders, but don't reallly help them much. The devs add very little content, and eventually start to advertise a new game they're more passionate about. Sound familiar?
The community for Cortex Command was as placid as it should've been. On the forums, people published mods or discussed mods, or gave help to fellow coders. There was an off-topic board where people would post what games they were interested in. There was some drama I think, usually from stolen assets, that was quickly arbitrated. Meanwhile on Blockland, you've got insane non-stop Drama, kids constantly private investigating themselves, rampant grooming, DDoS attacks, forgetin credit card theft?!? It's a Lego game where you build castles with your friends! Hell, Cortex Command was hyper-violent, all the enemy units would explode in bits of gore, talk about explicit - none of that rubbed off on the community.
Where do these communities differ? One of them has a hateful dev who constantly shows contempt for 8 year olds on his forum, and three moderators to control the posts of like 10,000 active users, and the other one had a larger moderation team for a far smaller community of posters, and devs who didn't use their forum as a sounding board for their misanthropic rants
