Please explain. I don't see anywhere on the page that it can't be distributed and reused as long as it's noncommercial. Am I understanding Tatoeba right? What does this mean?

Ok, I just changed the sentence.

The fact is the cc-by licence we use for tatoeba is more permissive than this, we do allow people to make commercial reuse of our data, so if the problem doesn't come from the import into tatoeba part, but from the fact that we also export our data, so unfortunately I think we will have to delete this sentence has we cannot respect the fact that it always stay non-commercial.

Look at the sentence again please. I don't think there's a problem anymore.

I changed it.
