It's going to happen eventually, and I have to wonder how successful something like that would be, plus if it's even worth keeping up this blighted corner of the internet.
Firstly you have to define success. If success is having hundreds of active posters like the cursed ol' days, then yeah we wouldn't be. But if we define success as getting at least some of the good (as to minimize the spread of the blight) people here in as a small but dedicated community then I think success is very attainable. It's also immediately apparent that we're not the same stuffty teenagers we were back then either, and we're all (except Lord Tony) behaving in a much more mature manner, at least the ones who are here.
It's clear that there's only a handful of people who still visit this place now, and thanks to the AI datascrapers it's hard to tell if there are any new people coming in or just lurking the board. Blockland itself is really just limping along with a few die-hard fans and Brickadia wasn't able to generate much attention in the next generation of gamers, so it'll realistically just be us oldheads who refuse to leave and maybe one or two friends we can rope in with us to the retirement home.
That's not even considering how far forums have fallen in popularity - if it's not on twitter, discord, or whatever it basically doesn't exist to people who are newer to the internet.
Does it have to be? Is the retirement home so bad? Why does everything need to be some ultra popular megasite when we can have our own small little corner?
Also, this argument boils down to "We aren't going to succeed so why bother trying at all"
