"if you had read the report"?
"weren't you curious"?
It should have been clear from my conditionals ("If this report is representative…"; "If other reports are worse…") that I was curious about the alluded-to prior history, and my analysis was contingent upon the (at the time unlinked) specifics.
The concern I still have is that this latest comment was so mild and non-insulting that one possible interpretation is that the previous warning(s) were working. He depersonalized his criticisms into the zone where, if judged dispassionately, they could be more more helpful than hurtful.
Now, you've also been quoting other incidents ("simians", "die die die") that might be more recent and salient. I can't find the context for those. (Searches only turn up this thread.)
But I am only opining on the exact comments and actions referenced here. I'm not defending any particular person (who I don't know), but one most recent comment. And I'm not criticizing a general policy of exiling recidivist assholes, only the act of pulling the trigger after a comment that, standing alone, is innocuous.
If someone else over the years posted a thousand comments with the same level of sarcasm and exasperation, but also the same level of actual useful info (and no insults), as in Mlynarik's most recent comment, would they get a ban? Or even a warning? I suspect not. They'd just be considered a cranky but useful bug reporter.
