Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

The following question which was migrated from, has been locked.

I tried to edit the question, because It could be written as

How Can I scan and get information from a bar-code using an Android Device

In my opinion, the conceivable way that such a question can be closed is by "exact duplicate", but It's not only been closed, but it's been locked.

According to What is a "locked" post?, A post can be locked when

  • A question or answer where repeated voting or editing is happening in a way which attempts to game, hack, or otherwise abuse the system.
  • A question that gets opened and closed repeatedly many times without achieving community consensus on whether it should stay open or closed.
  • A question that, for whatever reason, continues to attract flame posts, spam, or other inappropriate answers.
  • A question that is repeatedly vandalized by its asker; for example, to drastically alter the meaning of the question that invalidates existing answers, or to obliterate/obscure the question.

As far As I can tell, this question meets none of those criteria.

I can understand that the question was closed. It wasn't formed very well and It was almost certainly a duplicate, but why Locked?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Questions that are closed after a migration are locked by community.. I don't why though. – ɥʇǝS May 3 '13 at 15:35… - that's what happen to rejected migrations. – Mat May 3 '13 at 15:36

The idea is that you shouldn't migrate low quality questions. You should only migrate questions that are of high quality and will need little or no editing on the target site to be great questions.

When people start migrating crap just to get it off of their site then these target sites (i.e. the old programmers) end up just being a dumping bin filled with low quality questions. Worse still, these questions can just end up being migrated around and around with everyone playing hot potato with these questions.

This is a mechanism to prevent those types of behaviors. By locking questions that are closed after a migration it's a signal that you shouldn't be migrating a question unless you're sure that it will remain open on the target site; it also prevents the question from being migrated a second time.
