As other have said closing this forum would have no effect at all. You would have to close down any subreddit, detractor YouTube and Twitter as well, and even then it will not matter.
Phil has namedropped Kiwi a few times but he will always keep da trollz as a very vague entity, partly to avoid any of the pigs go and have a look for themselves and start questioning.
Neither is Phil above just making shit up out of nowhere and claim trolls have said and/or done them. So even if all trolls and detractors were to go away, Phil would just make something up to keep the victimhood and us vs. them narrative going.
We are not close to the end, I have no idea what makes you think that but it sounds like you might need a holiday from the vortex. Get away for at bit and if you still feel like it then come back, this shitshow will still be here.
EDIT:
Unrelated,
@Piece of Peace is there any way you could/would mark suspected whale socks in the tips tracker?
Also we can all pretty much agree that tipping is now almost an exclusive whale thing, right? Would it be fair to say that any non whales that are still giving Phil money (50BB) is doing so by Super Chats?
