As long as the Persian local thread isn't active enough, I don't think anything can be achieved in this thread.

The local thread should become more active in a normal way. If you ask people on social medias to join the forum just to make the local thread more active (as it seems you intend to do it), that will probably lead to spam. If that happens, be sure it will have a negative effect. Note that I'm not saying you shouldn't inform the forum to others. All new users are welcomed. But it's not a good idea to ask people to register to the forum just to make a thread active while they don't have anything to say.

There's a long way to convince theymos to add Persian board. There are some local threads with much more activity that still don't have their separate board.

Also, you broke the rules one more time.
It's not allowed to make multiple posts in a row.
