The brief answer is that posting translated coin announcements in Other languages/locations threads is off-topic and clutters the thread.
All Local boards - Discussion of various topics in the appropriate language. Posting translated coin announcements is limited to languages that have their own section (a.k.a. dedicated board with sub-boards).
If there's enough interest, a Pakistani board
might be added. Best advice I can give you right now is to help create an active Pakistani community on Bitcointalk, it's a long term effort and in the end the forum might help you expand in a board of your own. However, the latest local board created was the Philippines one, before it being created their lthread had ~600 pages.
