Can you turn off PS3 Trophies?

To rid yourself of unwanted throphies, one must create a brand new account with the PSN. This means losing all previous purchases made through the PS Store, and the downloads that are associated with the original account. This may mean eating tons of money, especially if the downloads are multiple purchases for GH or RB. Sad, but true. I do hope Sony adds the option to eliminate unwanted trophies. It can indeed be obnoxious to check one's trophies only to see those accomplished by other users who no longer use the console.
