Fewer users.
Once a site hits a critical mass of users the amount of content goes up and quality goes down. Once you reach that point it begins accelerating and turns the whole community to trash.
To be fair, this can be offset by sticking to smaller communities. All the large communities on reddit were low quality, but reddit’s large userbase allowed a lot of niche communities to exist with an acceptable amount of users. Lemmy (with its smaller overall user numbers) has much better “large” communities, but many of the niche communities barely have enough active users to get by.
