Thread:User talk:Ty/Why was my artidcle deleted?/reply (16)

Posting on most sites (including CP) is a license, not a copyright assignment. So you are giving them and others rights to use it, but they do not come to own it, and hence you do not lose your right to submit your contribution elsewhere. Now, if other editors at CP (or some other site) make edits to your contribution, those edits could put their copyright into it, which could mean you couldn't post it on a site with another license without their permission. If the edits are minor/trivial, this is a non-issue (copyright does not apply to minor changes like spelling corrections). And, if other editors make more major changes, you can reverse their changes to produce a version containing only your text, which you are then free to use wherever you wish.

So, I don't know the details of this particular case (since I am no longer a sysop I can no longer view the deleted contribution, ha)... but in principle, I don't see the problem with copying things you write for another site here, provided you pay careful attention to authorship and licensing issues.
