There's nothing you can do about that part. She took the portal and died and deleveled. Her action led to that, not theirs. They have no obligation to sacrifice one of their party members for her. You have a right to take a portal. But you don't have a right to be carried by anyone or be helped in there.
As for the harassment, you have total right to report that. But idk why I feel something is really off (and saying she quit the game not because of harassment, but due to not being raised and deleveling, doesn't add up and sounds suspicious, since leveling back doesn't even take more than 5min). I've done lots of runs with the discord group and never has anyone said anything in game to insult the sniper. Sure, some just used the slap emote or something, but never insulted the sniper. That itself is also against the rules of the discord group on Aether.
