where did you find the sentences? sentences collector, or on common voice website during record, or in the downloaded database?
I think it’s fine to ignore them, if the local community had no problem with it.
We had remove some Chinese Simplified sentences previously due to political sensative to local participants. If you find any sentences on Common Voice site that had similar problem, you can also report in the following thread.
If you found the sentence on Sentences Collector, you can just reject them if you feel the sentences will upset some contributor.
