I don't see why people are so convinced by text analysis when it's just text.
This isn't like Photoshop, where it is extremely hard to do a perfect job because any mistake, anything short of perfect can leave a clue. And you won't necessarily see those clues because they can get very technical, to a point where they're not even about how real the picture looks as much as they are about the technical intricacies of it. For example having the exact same arrangement of pixels on a given "texture" (A wall, a suit, whatever) in 2 different places is a near assured sign the thing has been tampered with, yet it can look seamless to the naked eye, or even when zoomed in.
Text analysis is just checking word frequencies, orthography, grammar, and a few other details, that's it. Go through the person's own text (And Phil has a Tweeter and Twitch history to make that very convenient), count word occurrences, common orthography and grammar mistakes/quirks, copy-paste turns of phrases, boom, it's just assembling a puzzle. And if you think you've missed something, just throw your text against an online text analyser; Until it gives extremely high probability, keep redoing. It's not like with Photoshop where getting someone actually knowledgeable to tell you what's wrong can be a bit hard.
And yes, this does require work, more than the page-editing people are saying the screenshots might also contain, but the point is, it's still highly fake-able. And if we're being honest, in this day and age, question's barely if something is fake-able, it's how hard it is to fake. Text ? Easy if you're ready to spend an hour or two on it. A number and a few avatars in a web-page ? 10 minutes top if you're just a tiny bit of a nerd.
Point is, these screenshots prove absolutely nothing. Doesn't mean they're fake, because Phil has taught us he absolutely is dumb enough for them to be real, but they're not evidence, neither in court nor in the abstract sense.
Does it matter ? Absolutely f#cking not. The DarksydePhil accounts that are on WWE Champions, Marvel Future Fight, and the Uselessness Discord have always been enough in and of themselves. Remember: "When you have eliminated the impossible, whatever remains, however improbable, must be the truth". What's the alternative, here ? Someone spent months, years, LARPing as Phil (With a similar model of phone, respecting his schedule to the letter as far as we've been able to tell) at the cost of tens of thousands of dollars, without ever even bringing any attention to it, just bidding their time until the moment if and when someone stumbles onto it ? Come on. It's Phil, we all know it.
