Carbon - Yes or No?

[kien]

has a tank ever crashed because it ran carbon: YES
has a tank ever crashed because it didn't run carbon: YES
has a tank ever crashed because it used bad salt: YES
has a tank ever crashed because it used good salt: YES
has a tank ever crashed because it was totally awesome: YES
has a tank ever crashed because a baby kola bear farted : YES

So, what I got out of this thread is that I should just pack it in now because my tank is going to crash at any moment (again).
