Requested feature overview description.
Contributor+: When selecting the "Explicit" rating on the upload page, automatically check the "Lock Rating" option. The rating-lock option can still be unchecked.
Why would it be useful?
Usually, content that is rated Explicit is unambiguous (visible genitalia, sex, etc.). Changing the behavior to automatically check "Lock Rating" when the rating is set to Explicit provides the following benefits:
1) It reduces the average amount of time spent per upload.
2) It would increase the number of posts that have their rating locked to avoid rating-change vandalism.
Since this behavior is limited to trusted users, it is unlikely that posts will be incorrectly rating-locked.
What part(s) of the site page(s) are affected?
