So, the way I see it there's a couple of things going on.
Dude being a douchebag, possibly illegally, possibly in an issue of consent
Dude appropriating funds/phone lines/etc.
These problems are kind of separate.
He should get kicked for #2, regardless. That's being investigated right now.
I feel very unhappy about his character due to #1. I cannot provide evidence. But seriously, let's put it this way. You're talking to a dude at a bus stop about random stuff. Video games, politics, whatever. Then he pulls his pants off, grins at you, and says "you and me... what do you say?" As implied, that's basically what he did.
This is about implied leveraging of power. In the real world, the power is the power men often have in this society to rape. It's different on the internet, where the implied power is political. Against any one woman, in private conversation, her word vs. his, he has immense leverage over her.
The reason why anyone can do anything is because he took it a step too far, by accident.
Nothing was done that requires consent. He just sent some racy photos, he didn't actually touch anybody or anything. That just makes him kind of a dick, not some kind of sexual predator.
Sexual harassment is about context.
So far as I can tell, this was sexual harassment. That harassment does not require touch.
