Over the last few days, user "ArchiT3K" has been asking questions about getting his Wi-Fi Captive Portal working with iOS. No one around here seems to know how to help him, so his questions never seem to get any traction. And yet he keeps posting new questions about the same basic issue, asked a little differently each time. It's possible that he's making slight progress on figuring out his own issue, but at some point it just seems like he's just cluttering up the site by asking many, many related questions about the same topic that no one around here seems to be able to help him with.
At the time of this writing, there are 5-6 questions from him about this topic that are still on the system, and I'm sure if a mod or admin could look at what questions of his have been closed, put on-hold, or deleted over the last few days, they'll find a handful more.
What's the appropriate way to respond to this behavior? Just let it stand? Politely ask him to give it a rest? Or does this behavior cross the line into something where the admins should step in to put an end to this?
