I have noticed a user asking the exact same question both on serverfault and stackoverflow. I'm referring to this question:

 [stackoverflow: importerror-no-module-named-xhaus-python-module-importing-error-from-ansible](http://stackoverflow.com/questions/38114393/importerror-no-module-named-xhaus-python-module-importing-error-from-ansible)
 [serverfault: importerror-no-module-named-xhaus-python-module-importing-error-from-ansible](https://serverfault.com/questions/787100/importerror-no-module-named-xhaus-python-module-importing-error-from-ansible)

To me it is obvious that the user placed to question on both sites to gain more attention. It has already been pointed out in other [questions](https://meta.serverfault.com/questions/8795/is-it-ok-to-post-a-question-on-both-stackexchange-and-another-software-specific/8797#8797) on meta serverfault crossposting is considered bad behavior, but I can't flag this question as duplicate because the flag as duplicate function gives me

*The duplicate question must exist on Server Fault*

I would like to see a clear guideline how to deal with those question and maybe it should be made possible to mark questions as duplicate when asked on other stack exchange sites.
