Why is the Arabic language not supported?

There is no doubt that idmb is one of the most famous websites in the world..it also supports many languages of the world..but I and other Arabic speakers are resentful for not being able to comment on our favorite movies in our language, why can't I express my feelings in my own language? Also, because the website interface is not available in our language, knowing that the number of Arabic speakers is more than 422 million people

Why is the Arabic language not supported in the comments or even the interface of the site?

*Note: Sorry for any mistakes, I use Google Translate
