I find this to be a rather strange take. Shouldn't this have been a feedback from Google to the developers, followed up by a swift change to conform, and everyone is happy?
The main issue here is lack of communication, and automated removals with little recourse from developers?
Complaining about this process does not seem like "immature whining" to me.
Why not give them some notice to fix it rather than just outright ban it on a Saturday? I'm surprised how many people on HN defend these hostile big corporation practices
What type of system would allow you report the user without the context? Banning users with consistent bad behaviour is much better for content quality than just removing content.
I don't agree this is immature, he definitely has a point that Google should consider giving even a day's leeway in cases like this. That being said, I may be in the minority here, but I wouldn't expect a button that's labeled "report user" to report the content of the message, only the user profile for things like an abusive name, fake profile etc.
