not sure how to address this seems like a multipart question
a DB location requires certain information and pics, hopefully pics you took and haven't stolen or downloaded from somebody else's website
if the location already exists in the DB, you can still add your pics
it does not matter if you found it on your own, read about it in a book or on UER or the tooth fairy told you where it is if you explored it you can contribute
if you have a more specific question you can always send a message to DB moderator Mike Dijital he's got the say so on DB entries being valid or not
