He's the IRL personification of the no life, fantasist neck beard forum posting nerd.
It's like in the arnie movie last action hero where the film characters find a way to slip into the real world. Blaha is an internet caricature that somehow bullshitted his way into being a "youtube celery" and succeeded in fooling the people for a while.
Once the first card fell his whole deck of lies crushed him like an avalanche. But he's such a shameless low life, that he keeps churning out 4-8 10 minute+ videos a day to get some poverty adsense money (in addition to his disability fraud).
