If you want to help the asker by posting his/her question at a different portal, I think you could do that, as context provided with the question should be non-confidential info.
You could include a link as a Reference comment to the original question on ProZ. That way the asker himself/herself can follow the responses at that other site, and you won't run the risk of getting accused of using somebody else's work to get KudoZ points for yourself.
One issue though, is that you may want to make sure the asker have not posted the question already on those other portals, because you don't want duplication.
I think this the best solution, better to provide link of original question as reference.
