Especially if it's only like $10.
If it's "only like $10" why not just make it right and get the trust ratings off your account?
Perhaps if the scam had been for $10k I'd see why you would not just cover the trouble. Just think of it as a $10 lesson to be more careful in the land of bitcoin, maybe next time instead of your forum account it will be your entire wallet of bitcoins that vanish.
