She's already been indicted on federal charges for hacking. Not being allowed to fly wouldn't be the main issue if she found her way into an American airport or airliner.
Reading that wiki page, it sounds like he's on his way to a long stint in prison, or worse. Wouldn't be surprised if he gets black-bagged now that he's attacking critical national infrastructure and encouraging others to do so.
Someone who continues to deliberately misgender after being told about it - especially using "he" when the person's name (Maia) is traditionally a woman's name - seems to care quite a bit.
If you use binary genders you use male or female ones and people tend to use the same pronouns once they start with them. If someone uses gendered pronouns you shouldn't take that to mean that's the one the subject prefers but rather that's the gender the person who wrote it perceived.
If they truly don't care to perceive a gender then a 50 / 50 pick. When I look at it's picture I honestly couldn't tell you if I perceive more male or female so I would've done same as op and picked one randomly and then for consistency not change it, even if some unrelated party tried to confuse things by making me change it.
Interesting hack, but this seems quite the brazen confession to a fair number of computer crimes. If I were the author, I'd be worried about getting arrested and potentially extradited for this. Especially as he deliberately downloaded a load of confidential information after gaining access, and then shared it around. He'd be looking at years in prison for this, in the US.
Switzerland's federal constitution prohibits extradition of swiss citizens to foreign powers. Now technically, this one amendment can be overriden by a mere act of Parliement, so unless there is a special act I'm not aware of, they are safe.
