IMDb Answers should have the ability to provide proof

Since additions are always so easy to be approved and IMDb Answers seeks for additions, this has a danger of creating more unreliable data imo.

Because corrections are always so much harder than additions.

Maybe also make it so that data that is contributed via IMDb answers feature is not that hard to correct as the data contributed via other means, because the data contributed via IMDb answers will not be a data that was supported with evidence anyway.
