It's obvious to me that there's a trend now on Stack Overflow of relatively low-quality questions from new users who are non-native speakers with low or intermediate fluency in English, or at least claim to be.
It doesn't take a genius to work out that this may be because some of them struggle to read and fully comprehend the various English-language notices and admonitions that Stack Overflow has put in place to try to deter low-quality questions over the years - from welcome pages, to automated content filters displaying terse rejection messages.
I am not saying that such non-native speakers always ask bad questions, of course - far from it! - I am saying that a noticeable number of the low-quality questions, are from such non-native speakers.
What could we do about this particular problem?
