So, a question about uncredited actors in films recently got bumped up after a year. It has one top answer with many (11 as of writing) upvotes. Even when it was originally answered, there were many comments asking about the answer (with very few good responses). After reading through it, the answer is pretty unhelpful (in my opinion) and the idea that someone would take no credit because they aren't getting a big paycheck is not only nonsensical, it's actually opposite to reality. Sometimes talent will be offered better billing so they will accept a lower pay.
So, I've answered the question with much more info but with only one downvote in my arsenal, I'm not sure what to do. Even after adding my answer, the old answer actually got another upvote...
I'm using this as a specific example but I've seen similar questions on metas on other stacks.
