I have noticed a growing practice of taking questions/answers from another similar site and posting them here. I don't have a problem with taking inspiration from a question/answer somewhere else, but just taking the entire concept and bringing it here for us to discuss kind of defeats the purpose of having the other site at all, and I believe it dilutes the pool of original content here.

To me it has a spammy feel. If the cross-poster is trying to cross-promote another site so we all go "check out" the original, then I feel duped. If he feels that the quality of the content on the original question (edits/answers/comments/whatever) is lacking there, then I don't think it benefits that other site to post the same question here. I'm not sure what the point is of the cross-posting. If it's to get the two sites to merge or work in tandem, I'm not sure what the end result will be.

Is there a policy about cross-posting material from other web sites?

If not, should there be?

UPDATE: This seems to be happening again. Does anyone else have any objection? If so, got any ideas?
