I am not happy with the way the sock puppets account are judged in this community. I have been targeted many times.
The place where I work, I try to encourage everyone to use stackoverflow, and post some questions, answer some question and most of them do also, but most of them they get bored too soon and leave the community. And to be frank, I do admit to influence them to vote my questions and answer few times.
So, from the moderator point of view there are multiple account from same IP, highly inactive, and voting same account time and again. I know it looks likes they are self inflected But still, they are not voting sock puppets, you cannot merge there account to mine, or simply remove them.
