Wrong link pulled into report when recording an exact duplicate on another SE site

Question

When reporting this question on SF as an exact duplicate of this one over on DBA, the description of question 2868 on SF is pulled through, not the description of question 2868 on dba.se.

The comment that gets added was (before I applied an edit):

possible duplicate of [What is the best open-source email solution package](https://serverfault.com/questions/2868/what-is-the-best-open-source-email-solution-package)

rather than

possible duplicate of [I am using a MEMORY engine but MYSQL still writes to my disk…why?](https://dba.stackexchange.com/questions/2868/i-am-using-a-memory-engine-but-mysql-still-writes-to-my-disk-why)

which I expected.

Is this behavior-as-intended (i.e. the feature is intended for marking duplicates within one site, and cross-posted duplicates should be reported some other way) or a bug?

As a side question: would it be worth implementing a distinction between questions from different users that carry the same meaning (which just want to be closed with a link to the older question) and cross-posts (in which case merging the answers, before closing the copies on all but the most relevant site, makes more sense)?

Answer 1

There is no concept of closing a question as a duplicate on another Stack Exchange site.

If a question is inappropriately cross-posted, flag it for moderator attention and it will be deleted.

Answer 2

Is this behavior-as-intended (i.e. the feature is intended for marking duplicates within one site, and cross-posted duplicates should be reported some other way)

Yes. In a general sense, it's actually fine to have questions "duplicated" across sites - provided they're addressing different audiences. Of course, if a question is off-topic, or if a user is simply re-posting the exact same question on multiple sites (cross-posting), it should be migrated to the site where it's most on-topic and dealt with there.
