Is this just jeets copypasting from chatGPT or other people's solutions?

I've recently started on it and, in the cases where there is something identifying nationality, LITERALLY EVERY SINGLE ONE of the comments I've seen on the site and on the r*ddit page is Indian. But the other thing I noticed is that the submissions seem to be unusually 'good', but only really in the sense of beating the metrics. Sometimes I will finish a problem in the most idea way that any normal person would use, then be faster than maybe 40% even after optimizing it. Then when I look at the other solutions the fastest ones are obscure hacks that very few programmers would know, totally different from the solution expected by the site, yet sometimes maybe 30-40% will do it like that.

Is there any way to see things like submissions by country? I would be very interested to see this but couldn't find any such breakdown on the site. I suspect the vast majority of submissions are done by people who have effectively zero actual programming ability. It doesn't really make any difference to anything it's still a useful resource, but I just thought it's funny. Some of the comments have solved hundreds of upwards of a thousand and can't understand really basic concepts. For what purpose? Why would they do this?
