I've always favored a smaller pool of federated servers. I know it sounds gatekeepy, but I'd go as far as not federating with any server that doesn't require an application to join. There's not that many Beeple, and it wouldn't take very much for someone hostile to our ideals to overwhelm us with sheer numbers. Just adding that little bit of friction should help immensely for maintaining our culture.
Of course, I don't expect this sentiment would be too popular, after all, there's a large contingent of users who want the biggest Threadiverse they can get. Furthermore, we'd get cut off from a bunch of communities if we did this. Perhaps we could consider a few more in house communities should we decide to go more isolationist.
Super Mario Bros. 3 was the first game I ever played, waaaay back in the early 90s. That hooked me into gaming for life, and every few years, I do a no warp playthrough of the game that started it all for me.
Then, a few years later, I tried Super Mario 64 in a Toys R Us. It blew my mind and I absolutely had to have an N64.
I despise Nintendo's business practices, but there's no doubt they had a formative influence on my childhood.
