My two cents, the board is fine and has arguably been fine for a pretty long time. I think the issue is a lot of people that don't regularly follow Phil have little idea of him. While the board is obviously pretty Phil focused, it also includes "the autism vortex" which is a broad way of referring to all the people that follow Phil.
Phil has a lot of a-logs, but none that are really regular posters on here. In no small part because we often say they're worse than Phil themselves. That's why we have a thread for them:
https://kiwifarms.st/threads/darksydephil-a-logs-general.17334/
Any of the "bigger" stuff, like bank leaks, escort or comcast guy were just randos. It's entirely possible they have regular accounts here and just used alts, but either way, it wasn't a coordinated effort by users on here. And half of those threads, with the exception of bank leaks dude, are usually either saying whatever happened was dumb or expressing doubt about the actual validity. Even with the bank leaks, I recall some posts about how it was a stupid risk, and I imagine the only reason there wasn't more pushback is it was largely drowned out by all the jokes about the expenses themselves.
What causes people to get into slapfights is when outsiders come in looking for fights and saying how we're angry/seething/coping etc, usually while going on about how we're raging because Phil played a game we liked poorly or because he got an unprecedented amount of money. Except nobody really cares about what Phil plays these days because it's usually SF6/it's widely agreed Phil's gameplay is too boring to actually watch even in clips, or it's just riffed on by a few dedicated watchers who don't mind doing summaries, but those threads are usually pretty quiet and have zero rage posts. As for money, eh, it used to be a way bigger deal when we were playing autistic detectives trying to figure out what Phil was actually spending on. Once that mystery was settled, it became a lot less interesting. Despite what some newcomers think, the amount of money Phil is pulling in lately is also a nothingburger because it's not actually as unprecedented as people think and I don't know if it even ranks on the top 10 list of Phil's big pulls.
I think there's still some impression that Phil is at the height of the SoK days. Who were also mocked on here, but hating on Phil was definitely more in style then. I won't pretend the boards have always been clean, there were a lot of alogs and spergs and it was generally seen as more acceptable to act like that. But I think they more or less left around the time of the bankruptcy saga, which was the last real surge of rage aimed at Phil specifically. But that was years ago at this point. Other than that, there's the odd angry poster here and there, but they tend to be randos and not really "one of us". Most of the Phil rage really seems to stem from YouTube and Twitter specifically, but for whatever reason, this board gets blamed for that. Which feels pretty unique, I feel like with any other cow, if there's people sperging out on YouTuber/Twitter/Reddit, it's (rightly) seen as an outsider thing and never blamed on anyone in the thread.
For actual regulars, I think Phil is sorta the modern day equivelent of watching Jerry Springer or a guilty pleasure reality show, like any of the Gordon Ramsay stuff where there's some bumbling, socially inept cook/hotel owner trying to be human on camera. I think there's been some genuine gold with Phil lately, PC build and putting up foam streams being the two biggest highlights, and I think those really explempify why people find Phil weirdly fascinating to watch.
