Is it possible to transfer my account reputation to anybody? If it is legal, how? Because if I want close or deleted my account.
If I deleted my account, what would happen to my account points, privileges and badges, etc.?
If your account is deleted, everything associated with it will be gone.
They will not be "transferred" to anyone and shouldn't be - reputation is a measure of how much the community trusts someone - if you didn't "earn" it, you shouldn't get it. Sometimes, when we delete accounts that were very active, we transfer votes and such to the community user, so the community itself doesn't get disrupted.
If you do feel like "transferring" reputation, offer bounties. But give them to posts who deserve it.
