I know this is super obvious and has been said about a thousand times before but it's still really baffling to me how he's so blatant about this. How is he not ashamed?
While he occasionally tells his Twitter followers that he lives with his mum, he doesn't tell them that he's in his mid-30s and has never had a job. To put together all of the various pieces of information which reveal Jake's life, you'd have to read an awful lot of his Tweets - and ain't nobody got time for that. If anyone does ask a question trying to clarify conflicting information, he just dismisses them as a "nazi" and blocks them.
While Jake really does view himself as a victim, part of his motive for denying his true identity is based around knowing he'd lose supporters if his followers accepted the truth. "Nazis" aren't a direct threat to Jake in any way - as evidenced by him not having received so much as an unwanted pizza since he was doxed - but they are a potential threat to his credibility and he knows it.
