It is not a sock puppet, but is an account which is used to make edits with AWB.
All edits are manually previewed & saved. The operator will usually trust AWB's recommended cleanup suggestions.
If this user makes a mistake, and it isn't corrected within a reasonable amount of time, please leave User talk:Od Mishehu a message. If the user seems to be in the process of making bad edits, please follow this link and leave a message on this user's talk page. Any such message will be moved to User talk:Od Mishehu; if any urgent followup is needed, please just leave a {{talkback}} on this account's talk page, and leave a message in the thread on the operator's talk page.
Occasionally, this user may purposely include what appears to be a mistake, to be fixed immediately afterwords, if the operator believes that the "mistake" in question helps document what he believes to be a bug in the software.
