At best this would be a positive change and at worst a neutral one. Adding an additional bucket may help lots of folks. This is a difficult one in that most of the, “I got hacked” narratives tend to center around circumstantials. Suspicious behavior is neither malicious nor benign until it’s been investigated and understood. One of the best forcing functions for growth in my career was (and frankly is) participating in communities where evidence is an informal requirement for participation. The Internet, like metaphysics in a sense, is a weird place where anyone can say anything and get away with it. Unless the community decides otherwise.
I propose a section around supplying evidence be added to Welcome to the Qubes OS forum!.
It could read something like this:
Provide Evidence
When discussing technical issues - it is strongly advised that evidence be supplied. These can arrive in the form of error messages, appropriately redacted log entries, or other forms of technical details.
If this is an acceptable contribution, perhaps it would be part of the Help us help you section or just below it.
