I think there's no problem with this, although I'm quite sure that we won't actually delete many sentences because it's hard to decide that a sentence is absolutely unnatural.

I find this great!


There will still be at least two problems.

First, when a sentence has several translations, both owned and unowned ones, you'll need to visit each pages to see if the sentence is owned.

Second, even if you don't show orphan sentences as a random sentence, they will still show up frequently as a translation of the random sentence, which will likely to give native Japanese speakers the impression that this must be an unreliable website.

I think you can solve them both by making a new option "Display orphan sentences" in the settings page and set it "off" by default.

I'd like to ask you if you really want us to spend our time deleting bad orphan sentences. I feel that adding new good sentences would be much more rewarding and profitable. There are so few native Japanese speakers here, and it takes much more time to judge whether a sentence is bad enough to be deleted than to make a new sentence (at least for me).

I agree that owned unnatural sentences must be changed or deleted, but I'm reluctant to approve the idea that we delete bad orphan sentences. They will go to the "low reliability database" in the near future anyway, won't they?
