I noticed that lately there are some questions asked here, not written in English, that really are example for the proposal, or questions that should be asked on the site, when it is created.
Should not be there a filter that blocks low quality questions, similarly to what done in Stack Overflow where questions containing only code are blocked?
If there is already a system to assign a quality value to posts, should not the method to valuate the post consider the following questions as low quality posts?
"For older parents in Europe and America and Taiwan, which is more suitable for Chinatown? Friends how to look. Or experienced friend to share. Thank you"
"A few years ago comes in to say, the situation is now somewhat reversed? European and American countries economic stagnation, is likely to double dip, high unemployment. In this context, local hostility to foreign immigration is also growing. Although the Chinese economy has problems, but at least still in rapid growth, the demand for IT personnel is also very strong. This time migration, the timing is a little problem? In fact the U.S. occupation of Wall Street campaign, Europe strike, show that local people's discontent is unusually severe."
"U.S. computer industry is very advanced, it should be for the farm yard is the most appropriate destination.
There are many immigrants currently looking line, which are more suitable for agricultural code it? Many immigrants to cross the barrier, language, culture, discrimination, loneliness, etc., not to say that moving out is needed. This should be a deliberate decision."
"Buzz today just to see the news on the United States passed a bill to cancel the visa quota restrictions in the country benefit from the large Indian immigration, if through the cool."

If it is not possible to filter those low quality questions, should not be there a reminder for users with low reputation? That is what is already done for beta site, where the new users see a reminder about how to ask a question (and this happens independently from the user being already a 10k user on another SE site); for Area 51, the reminder could be show for low reputation users for the first, e.g., four questions asked, or for a number of questions that is calculated basing on the number of questions asked per day by that user.
Edit: I notice that there is a review tab, on this site, and I see the questions I am referring are marked as very low quality. Maybe such questions should cause the OP to see a dialog asking if they are sure they didn't pick up the wrong site, and reminds what the purpose of this site is.
