I don't think you're in the minority there. It seems like there are a lot of player (and team, or both) collectors out there. I know I have both, and I use the filters all the time. And yes, there are cards I have that aren't listed.
There are exceptions to adding the TBD/TBA info in sets, and that's when there has been extensive research already done. A minor league baseball team set from 3 years ago will be found soon enough. One from 1932, maybe not so much. Admin has allowed them, and some have been added without approval. I have a user list with the ones I have found (or have been alerted to). A few that were on the list have been updated and subsequently removed from my list. TBD/TBA should be used only as a last resort, when all other avenues have been fully exhausted - and the set is a known quantity of cards.
