The fact is, I think there are a handful of non-native English speakers who have commented that I have marked as spam, when they were just trying their best.

Still, I think this video is beneficial for them as well. When I comment in Spanish, my Spanish is not that great, yet I still try to leave a decent comment, even if the grammar sucks. I know a lot of users are using the "google translator" app, and that's a decent go, but it's causing some problems. It often looks like spam. So I generally try to look for more than one indicator before I flag people, for that reason alone. I don't want to discourage a non-native English speaking noob before they get off the ground.
