Whose filmographies are they anyway?

Even at the risk of being branded as nitpicking, I'm fervently driven to point out the fact that the first amendment to the Constitution of the United States only prohibits the ratification of law allowing for people to be sentenced to death, imprisonment, forfeiture or any punishment at all, likewise convicted, prosecuted, jailed, fined, indicted, accused or taxed to begin with, for expressing themselves, their faiths, their conjectures, their hypotheses, their theories, their mockeries, their parodies, their criticisms, their grievances or roughly whatever. In no way does the first amendment impose an obligation upon anybody to publish or propagate any form of expression, let alone to carry somebody else's expressions. If anything, the first amendment prohibits such a thing from becoming the law. Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances. Which is pre-reenforced by the fourth article of the Constitution of the United States: The Citizens of each State shall be entitled to all Privileges and Immunities of Citizens in the several States. Which is reiterated in the fourth amendment to the Constitution of the United States: No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws. The long story short: nothing about a person's ability or inability to supply his or her filmography details to IMDb has anything whatsoever to do with the first amendment to the Constitution of the United States, unless that person is trying to invoke a statute, a treaty or other law inferior to the Constitution yet contradicts the Constitution.

The process to submit content to IMDb has not changed in decades and is the same regardless of whether the submission is sent by an actor, or a producer, or anyone else: submitted data is processed by IMDb staff and accepted or rejected, typically based on a number of criteria which vary depending on the credit itself, the reliability of the source, the title being submitted to etc. If you have submitted a credit and it has not been accepted, the most likely reason is that we were not able to confirm its eligibility to be included. This could be due to lack of availability of the title or lack of evidence provided with the submission, or a number of other factors. If you have had problem adding credits to your page, I recommend trying again and including additional evidence to support it.
