There is only one way to find them.
Go to the Explore page and sort videos by language, choosing Telugu. Then go to each drama or movie (as you see, there’s only five of them!) and look for the Team tab, where you can see the names of all moderators, including those for Telugu. Then you can write to them (in both English and Telugu), saying that you want to contribute, that you are new and have no Viki pass, and everything else you want to say.
