Great stats. Nice infographic.
I'd like to point out that this is good news. I read a scary thread on here where people are getting away with plagiarism by using Cyrillic characters in place of normal Latin alphabets.
The Cyrillic characters would fool the copyscape system, and google, into thinking the content was unique, when in reality it wasn't. So there are apparently tons of posts that have flown under the radar because some of their letters are Cyrillic, but the rest are otherwise in Latin.
They made sure to switch out common words, like wallet, because those are the ones with higher density in posts.
But your stats show that only 11% of these posts are Cyrillic, which means that perhaps only 2% of that 11% is the kind that abuses the forum with plagiarism. So that's really good
