I've spent years living abroad and have had many long discussions and friendships with non-native english speakers.

This could be a non-native speaker, but the complexity of the attempted sentence structure leads me to think it is a native or fluent speaker who made some mistakes (I make those kinds of mistakes all the time.)

English speaker for approximately 43 of my 44+ years on this planet. I have almost no idea what this sentence is trying to convey.

"You are probably not very exposed to non-native speakers."

If native speakers have to talk to people of other languages to understand it, then it's not even English at that point. What it is, who knows.

I am non-native speaker and I confirm that the post was gibberish.
