IMDb Rejected My Accurate Corrections of Blatant Errors on a Cast List of a Hitchcock-directed TV episode

There is an obvious error on the cast list of the Alfred Hitchcock-directed TV episode, Incident at a Corner (Startime, 1.27).  Two actors are credited with the same role.  On the cast list taken from the screen credits, "Principal Rigsby" is said to be played by Alexander Lockwood (as indeed he is), but some careless IMDb fan, in the lower part of the cast list (the part not from the screen credits but added by IMDb users), has added "Wendell Holmes" to the cast as Rigsby.  Seeing the discrepancy, I spent about 20 minutes locating a massive number of pictures of the two actors on Google Images, and compared the pictures to my own DVD copy of the film (which I watched twice tonight), and verified that Holmes does not play Rigsby.  So I submitted a correction, pointing out the logical impossibility of two actors playing the same character (who appears in only one brief scene), and submitted the links to the Google Image pages showing the obvious difference in look between the two actors, and argued that the onscreen credits -- following IMDb rules! -- should take precedence over conflicting claims made by IMDb users.  

My correction was rejected.

Now it might have been caused by the difficulty of reading Google Images links, which are massively long and made my submission hard to read.  If that's the case, someone could have written back and said, please resubmit without the massive links.  But instead my correction was just rejected.  Yet it's obviously correct.  So right now the cast list has two actors playing the same role, with the second actor being wrong.  

When the erroneous Holmes addition was first submitted, it should have been caught by IMDb and rejected because the character was already on the cast list.  

I have also submitted another deletion to that cast list, again an erroneous addition by an IMDb user who either has not seen the episode or has seen it but incorrectly added a non-existent character.  There is no "Mrs. Sidney" in the episode; nor does the actress Hollis Irving appear in the episode.  Someone has obviously misread "Mrs. Sinden" as "Mrs. Sidney", and then got the actress wrong for the part.  Again, I submitted links showing multiple shots of the real actress and indicating that she is the one who appears in my print on the DVD, but again it was rejected.  The problem might be the long links to Google Images.  Does anyone know how to refer to a Google Images page with what used to be called a "tiny URL" that is much shorter?
