It's a little hard for me to parse wanting to kill ones' self over trolling, but then again, my perspective is different. I love getting approbation for the few contributions I've made and posted online to my hobbies. It's nice but not critical for me. It's never really happened, but If I got trolled, change the channel, whatever. I have a ton of IRL going on - Kids, wife, dog, pinball machines, etc. But, If I was in poor health and isolated, I know the online life would be a much bigger thing.
I speak out against hate and personal attacks on the net in the infrequent situations that come up, and I don't support or use 4chan or reddit. My sympathy to her family and friends. Sounds like she was the type of dev that every project needs and doesn't have enough of.
