Ok as it explains the discolouration then it does not explain the damage to the earth pin, although as you say it's second hand plug this could be from before it was used on this item.... if indeed it is a 'metallic' paint as you suggest, it is possible the paint itself acts as a conductor, these metal paints do contain metal diffused into the paint itself, again it won't show the timeline here and could be a past issue..... what is worrying is the earth pin been hot, if all pins were hot then its probably heat conduction if it only effected 1 or 2 pins then you have to look deeper into the causes.
