Maybe I've become overly paranoid during my years on the forum, but MAN has your English improved since 2017

when I see a post history like yours I just kinda scratch my head and wonder.
I was terrible at English in school, but "the internet" (and travel) taught me more than school ever could. I have no doubt some people are cheating, but it's totally possible to improve your English skills in 8 years.
