I went back to see what the problem might be, and I believe your posts are too long!!! They are at least 4 paragraphs long and it takes a while to correct a text.
In the old version of italki, I would actually search for texts that had zero corrections, and most of the times, the texts were like yours---very long; I would sit and correct them, and it would take me sometimes 30 minutes to an hour, and like most people, I have other things to do.
Also, looking at your text, I can quickly see that a lot of the time correcting it would be spent on finding the best way to say your sentences.
Take this sentence, for example:
I think the most problem we can notice about to get comfortable with speaking foreign language is not to find partner to speak but to come opened for using language freely.
(The biggest problem about learning a foreign language is not finding a partner to practice with, but actually speaking the language). I had to think of this sentence in less than a minute and I still think is not 100% close to what you're trying to say.
I understand the idea you're trying to communicate and at this point I'm thinking...what's the best way to communicate this idea as a native English speaker so this actually takes a bit of time; is not as easy as somebody writing,
The apples is green. This sentence is easy to correct because all that needs correction is a verb. The apples are green.
Your sentence is more complex, and it requires a lot of time to correct it, and that's how a lot of your text is: long and complex, and that's why I wouldn't correct it---too long, too complex, too much time.
My suggestion to you would be to submit maybe one paragraph at a time because smaller texts have a higher chance of getting corrected.
