What kind of stupidity is this?
If you don't want the items just discard them from your inventory. Merely having some of them attached to your account won't do any kind of harm to anything.
Somehow removing them from your account won't change the fact that you did buy them previously - and you know you did, so any embarassement should still be there.
Removing those items from your account isn't taking a stand, it just being silly. Nobody else will see that you have removed them, nobody else will be impressed by your actions, and the money you spent will still have been spent.
