I’ve just suggested an edit to a question which used xyz.com as a placeholder domain name. Lots of people are unfamiliar with RFC 2606, and therefore use domain names other than example{.com|.org|.net} as placeholders. Such domain names are blocked from use on Stack Overflow according to a policy discussion, so why can they still be used here on Server Fault?

They should be blacklisted here. But the blacklists are site-specific, not network-wide. They're also not something moderators can touch, so someone from Stack Exchange would have to add them.

  • Blocking stuff like mysite.com may block some legitimate questions (specifically, ones where the OP cites a tutorial written by someone who has never read RFC 2606). Whether or not we want such questions is a matter for a different discussion though.

  • Hmm. I can't remember ever seeing a question that would have been blocked in that rather narrow scenario. Do you have one handy? Commented Jun 4, 2014 at 20:55

    not off the top of my head, but I know I've seen tutorials and config examples use mysite.com (it seems to be a popular one). Personally I have no problem with blacklisting these domains though - PROFESSIONALS should be familiar with RFC 2606.
