Yes, I did, but keep in mind that when I uploaded 60 of them there was a bug so I uploaded even some sentences with acronyms. To be absolutely sure all the sentences accomplish the rules, I would need to remove the Basque sentences from the Sentence Collector. That option exists? If so, I don’t know where.

Can you coordinate with @mkohler to test all your sentences through the sentence collector? We should make sure the PR doesn’t have these invalid sentences.
