See here for the detailed complaint. We know that you're working on an improved credit system, but it will take a while. Here's something you can do in the meantime that won't require a major overhaul: Make accepted birth-years apply only to the profile where they are accepted. Since the whole reason we are propagating birth years is that there are other people with the same name, applying the year to everyone with a given name is guaranteed to result in lots of errors, which cause problems for basically all end0users who care and sometimes get into the online database.

Ideally, there would be some tool that would tell us what names exist in a form both with and without year so we could check the unyeared ones and apply the birth year as necessary. This would need to be combined with my previous suggestion to have a function to replace all instance of credited A on flagged profiles with credit B to be very practical.
