Background Performers getting "Uncredited" credits

I'm not understanding this flood of "Uncredited" names coming up in the cast?   If you had a line or were a Stand-In, or stunts, dancer then you get a screen credit.  Its confirmable.  But I have been seeing tons of "Uncredited" that are Background Performers.   I know some as it's movies I have worked on and know they are not speaking rolls, or specialty, just someone who created a name like "Class Teacher" and put it up.  I'm not unsympathetic, just there should be a fix.

This is still a continued problem.   I understand people wanting credit, but we use hundreds of BG in a Film / TV Show or whatever.  If you speak you get a screen credit (if it's SAG, not always the same for Non-Union) and could be checked by the end credit's.  If it's a star actor doing a fun cameo and it can be confirmed then that is fun.   There needs to be a solution, with the problem being you can't certify a BG person.  They are BG, which makes them a part of the film but more part of the Crew, not cast I feel.   But since again you can't confirm this, then they either shouldn't be allowed in the "Uncredited" or set up a Background Performer section.   It really has become a little silly.   I have even seen people at comic con who are BG performers with no screen credits or a ton of "Uncredited" setting up a place for autographs.   I have worked with some and know they are BG and not a speaking cast member.    Please find a solution... I know there is a thread only started 10 years ago... so I guess we will see.

I'm interested in hearing thoughts on this if you have opinions, but be open minded and kind.  Lets have a talk / discussion, not rudeness.
