Mirror sites

I just read this:

Do not submit mirror sites. Mirror sites are sites that contain identical content, but have altogether different URLs

Multiple submissions of the same or related sites may result in the exclusion and/or deletion of those and all affiliated sites.
Exclusion or deletion from dmoz or from google?

From DMOZ, and therefore from the Google Directory.

Not from the Google search engine.

However mirror site is one kind of Black Hat seo tactic so later on search engine also will exclude that site from their result.

We can't comment on the policies of search engines, only those of our own directory .

Note that the ODP has a broader definition of "mirror site" than search engines do. my-red-widgets.com and my-blue-widgets.com would be considered "fraternal" mirrors (compare the expression "fraternal twins".) They aren't identical, but they both are front ends to the same company's catalog database. They may display different PARTS of the database, but that's irrelevant.
