1.x decades later, I regret it. I get people's medical information, legal documentation, all of it. It is stunning to me the quantity of PII that flows into my inbox daily. Back when it was a trickle, I used to try and contact the people involved to let them know of the issue. It almost never worked out, and I got tired of getting yelled at.
At this point, I keep my account simply because if I were to close it, I don't trust whomever might have it next. It is what it is.
