Sorry if this sounds a bit like an often asked question:

A recent question about ps which was already answered in SO , according to comment, Cross posting was OK.

When I cross posted (U&L (deleted) and Sec Policy) a while ago, I asked about it , and policy was not to cross post.

So is cross posting ...

  • allowed
  • frown upon
  • tolerated
  • forbidden
  • strictly forbidden ?

Cross-posting is not allowed and is frowned upon. However, cross-posting only refers to posts by the same author. If you ask here and somebody else asks on SO, that's not cross-posting. In the example you cite, the OP here was not the same person who'd asked on SO so it's not a cross-post.

Personally, I feel that the SE community is a bit too obsessed with cross-posts and that it's a mentality left over from the days of the trilogy (SO,SF and SU) whose scopes were much clearer and with less overlap. Today we have sites like AU, U&L etc. whose scopes are very similar and it would, in my opinion, be a good idea to have a mechanism to somehow link Qs from different sites or allow cross-posting or something but I seem to be in the minority.

In any case, at the moment, community consensus is clearly against cross-posts so no, they're not allowed.

  • Please clarify: I recall reading the it's OK to ask a question on one SE site and also one or more non-SE sites.  Is that correct? Commented Sep 14, 2015 at 15:41

    @Scott sure, non-se sites don't count. We can hardly demand that someone posts here and only here. Cross-posting only applies to multiple sites of SE

  • Yes! If we could flag questions for moderator to decide if the question can be displayed on two or more sites, life would be so much easier!
