General Rules

The following credits are likely to be discarded:

• Submissions with an empty character field or with descriptions such as "lead", "supporting" or "featured".

• We will accept "background" or "extra" if that's how the credit appears on screen, but "background", "extra" or "bit-part" will not be accepted as a character name on the title if the role does not receive an on-screen credit. If that is the case the character name should include a description of the part - Woman with Dog, for instance - and (uncredited) in the 'attribute' box. But see below - they must be recognizable.
• It is not enough to have just worked on a production: Their scenes must be included in the final cut and it must be possible to easily identify their appearance.
• Background/extra work as a crowd member (or a similar role where it's impossible to recognize the subject)

We will usually discard credited submissions where, in the vast majority of cases the character/role name would be uncredited, such as "waiter", "bus driver", "pedestrian", "bar patron", "party goer" etc. If they are credited with such a character or role name, you are able to provide evidence and the credit does not appear on the site within 10 days, please contact our team using the form below with verifiable proof of the credit.

Please also note that we place a lot of weight on submitter history, so submitters who have previously attempted to submit false information, such as listing an uncredited role as credited, will find it extremely difficult to get future submissions accepted. Please see the Contributors Charter for more information.

I went in and deleted the credit and IMDb has accepted it.

This has been frustrating for me, as well.  I am working WITH THE PERSON INVOLVED (who does NOT have an IMDbPro account for himself).  Some helpful fan added a whole bunch of his amateur films he made when he was a kid, and he's asked me to get them deleted OFF of his IMDb.  In the last round, I even provided his direct email contact for IMDb to reach out to him if they need verification.  What REALLY puzzles me is that, for a title to even be added, IMDb *supposedly* requires some indication that it has been made available to the general public, and not one of his amateur films ever received that (not even uploaded to YouTube).  I could see a single title getting past, but 40 - 50 of them??  REALLY, IMDb?  That makes it all the more frustrating for those of us who ARE working professionals with a lot of projects in development (and not even a release date yet) who would like to get projects added.  Can't even do that with serious work that IS forthcoming, and yet some yahoo can put on someone else's profile 40-50 projects which never became available to the general public?

Post some OBJECTIVE criteria and then stick to them, please.  I'll try the "delete a title" route, but man that's going to be a lot of work for me that I don't really have time to do.
