Online it is harder than in real life to spot a shizo, but there is a dead giveaway that never fails, even when they aren't having an episode and could easily pass for a somewhat sane person:
It's a certain manic way of communicating, impatient, fast to anger, an urgency to get everyone on board with whatever thought possesses them at the moment.
Once you know it it's very easy to spot.
