Assuming a user registered a second account that only answers the user's own questions. Could they be merged by the user's request? Is that against the TOS and would be punished?
@nhinkle I think the user's contributions are valuable, although primarily his questions, so I don't think he should be punished (except losing the self-upvoted rep).
Hm. Pretty minimal overlap in IPs, no suspicious votes. I'll make a note, but not going to do anything about it for now. They might just be friends or something.
@nhinkle A friend doesn't answer exclusively your own questions on some web site, within minutes, every time. Or link to your own blog as quickly accepted answer to your question...
But as I said, maybe he just needs to be made aware that it's OK to answer his own questions, and I left a comment about that earlier.
So you could merge all the accounts if he asked about it?
I'll look a little more, but at this point, there hasn't been enough overlap to cause any significant rep alteration, so we don't really need to intervene. Let us know if he does end up requesting a merge though.
I agree that the circumstances are a bit odd, but it's not abusive, so I'm not inclined to intervene for now.
(FWIW, he's actually accepted more of your answers than of his "own")
