how to delete credit

Ok. I will ask again.  All I got is one trolling accusation from a community forum member saying they do not  think we will  post entire films to show we are not credited because they  know we were in them and that is what happens when you regret what you filmed.

We are seeking help, not the community forum  calling us liars.   Seriously, social media is still not an acceptable way to just speak your inner most judgmental thoughts of humans.

There is no film even with this title, only some goofy rock videos or music videos with no film  credits  found on you tube. 

So, where do we post these videos to show that someone is not in the film? And that there are no film credits? Do I  have to  post all these videos of bands to prove this?   And how does that prove someone is not in the video if IMDb does not know who they are?

There are no credits and this person we are trying to delete is clearly  not in this video!   We think  the name was added later by others who  were mistaken.  The name in question here would have been  for a child about 5 years old at the time the video was made and clearly that is not  this person in the video..
