I know this is many years too late, however I'm really shocked you gave such a lovely, usually well tempered snake away that have such character all because you were stupid enough not to use tongs. I have a lovely hoggie who has hissed at me and hooded but once picked up is so calm. Not once have I never used tongs with any of my snakes and not once have I been bitten.
Please don't be telling people to be careful with this snake, you're more likely to be bitten by a corn or king snake (which are said to be beginner snakes) than a hog it's just if you do get bitten by a hog its possible you'll have an allergic reaction. They're lovely, lovely snakes nobody should be scared or put off. Just like any other snake, when feeding they may get a bit excited which is why tongs should always be used.
Like someone else mentioned here, I'm lead to believe that a bite from a hoggie develops depending on whether you are allergic to their venom. Seems you were unlucky. Please everyone use tongs when feeding, never become complacent.
All I can say is thank you for not blaming the snake and admitting it was your fault...but since you've admitted so, the snake shouldn't have been given up as, if you'd follow proper protocol it shouldn't happen again.
