(and, I believe, a couple more besides) have the following characteristics in common:

• They've all joined in the past few days.
• Each has asked exactly one question
• Their questions are closely related to each other
• Their writing styles are very similar
• After posting their questions, they never return to engage with commenters, or to acknowledge answers

I think it is not too much of a leap to conjecture that these are all the same person.

As far as I know, there's no actual rule against having fifteen different identities (or for that matter, a hundred, as seems likely if this keeps up at this rate for a few more weeks), and no actual rule against asking questions and then systematically ignoring responses, but I still find it troubling in ways that might or might not be entirely rational on my part. Do others share my discomfort?
