@matana like, fair enough.
For me, there's a point when you should just leave or not use the service. I don't bother leaving reviews, because there's no real point. It hardly ever leads anywhere.
It's just annoying when someone says "I left a scathing review before I cancelled my account", and I'm just like "really?"...
I view it as a pathetic power-trip. Then again, I view most of what Boomers do as pathetic power-trips.
