What's tough for me as a newbie admin is that I had never encountered this venting obsession behavior before. So my first impulse was to give it space and console the person venting extremely heavy topics. I think a lot of people's first impulse are the same.

At the end of the day, I think rules are necessary because of the fact that these online spaces arent actually communities. Rules should keep venting to every day things. And while people (or maybe just people like me) respond with sympathy, the sympathy isnt real unless you know the person. I've had a person I helped during these vent sessions turn on me because when they realized I was assisting only out of obligation, they got even more upset. But I don't know them and can't magically manifest feelings out of nothing. Even tho I wanted to help.
