verifying actor credits
For a few months I have been updating actor credits from a drama series which I have watched from official DVD's. Edits have been for changing spelling of character names and for where actors have been credited/not credited for episodes they did appear/not appear in. The series lists all its regular actors on the end credits even if they don't appear in the episode. Semi-regulars are often listed in the same way.
Lately my submissions are mostly being declined. I could provide screenshots for verification of the character names. How do I provide verification of whether an actor was in the episode or not?
Any help would be appreciated. Thanks.
