I'm actually coming around to the theory that Linda and Dave visited him. Maybe not a surprise visit but something that was in motion for some time now. Yes. Phil says they're on their deathbeds but Phil is a faggot. Dave was out fishing. Hopping on an aeroplane for a few hours won't kill him. That would explain the aggressive exponential increase in begging. Trying to prove to mummy that 'no, the 10 year plan wasn't necessary' and he's super sussessful actually.
But what I like about this theory is they see how he's living and find out that he's been bullshitting them this whole time. Or maybe, if Kat is there, they see what he's done to her and have a row. Fuck I wish that had been an option on the poll. After Social Experiment THIS is the best theory.
And as for why he isn't posting shit? A combo of not wanting the trolls to make fun of Linda's smoker cough and being embarassed of being an Internet edgelord (as Stuttering Craig put it). So he just hides everything. Remember when he had that fat lady on and all of the sudden all his normal goals went missing? All of his usual berating of the chat was turned into silent bans? He knows he's a damn loser and would try and obfuscate/censor it all. After all Kat was giant canary in the coal mine for this. If she can do it so can he at least for a week.
