I'm afraid I disagree.
If one asks 'can something be done about...' it is clearly a request or call to action.
If one asks can something 'not' be done...' it invites the interpretation that, in fact, no action is required.
The point, tautologically, is that the latter, as it appears above, can be interpreted that way. The 'not' is quite unnecessary and the sentence is much more logical when it is removed.
But I suspect that we have a divergence here - those of us who have, perhaps naughtily, chosen to respond in a humourous vein, and others who have approached it from a grammatically correct and purist perspective.
If nothing else, it has sparked some debate and as either is correct, 'vive la difference!'
And I still do not like goats.
