No Advocate involved or needed. Phil himself is a categorical, habitual liar with a history of dishonesty so long and so random that in my opinion it
only makes sense to demand evidence for any claim he makes, even one as innocuous as what he had for breakfast*. Couple that with the fact that the Autism Vortex is powerful enough to at one point have roped in a catfishing couple from another continent and I don't think it's at all unreasonable to suspect anything unsubstantiated that makes Phil look bad.
Without at least some profile info that would indicate the age of his account, etc., as asked by
@actually I can't help but be skeptical. Yes, we know Phil says he plays the game, and with his documented interest in wrasslin' and previous discussion of playing mobile games I believe he does. But that's not enough to make me believe an account bearing his traditional handle is necessarily him. People have and will continue to go to extreme lengths to make him look bad, an activity that flies in the face of all reason because Phil makes himself look bad enough as it is every day of his life, and there appears to be no switch which can be flipped that will cause his supporters to walk away en masse. It doesn't stop crazy people from trying, though.
I'll concede that the simplest explanation is indeed that it's him, however. After the Mystery Woman arc, though, I'd argue that doubting Thomas's have a role in things here, and that questioning validity is a good thing, with DSP and writ large.
*not that I'd ever expect anyone to go about screaming demands for said proof. Only true autists need apply
