Netanyahu's Persian Twitter is Full of Mistakes!

Last week in New York Times I read Israeli Prime minister Benjamin Netanyahu has launched a Persian-language twitter. 

It's good and hopefully an effective way to communicate with Iran's people but I am quite surprized why the content of his Persian twitts is full of mistake?!

Two of them have been shown in the above screenshot. The mistakes are both grammaer and spelling. 

Should I believe that there is no Persian-speaker to edit the posts for him?!
