If you don't have a check valve between keg and regulator, and you over-pressure a keg, that keg pressure will back-feed the regulator, such that if you dial down the regulator the low pressure gauge will read the higher pressure provided by the keg. This can confuse the novice (and we read about it all the time here).
As for blowing out the reg: folks buy brand new regs that are laden with machining debris that gets into the valve and causes exactly that "creep" syndrome. One person posted a pic of his new reg and the inside was caked with brass bits...
