Problems with chessdb.com.

1. Why have all the games of certain masters/ grandmasters mysteriously vanished??

2. Why are there multiple databases for the same person?

3. Why do I not have a profile despite the fact that 2018 is my fourth year playing tournament chess?

4. Why do profiles exist for unrated or very low rated beginner kids who have not played the game in years, while myself, an active class B player who plays tournaments on a weekly basis has no profile?

You should ask them, not chess.com 

As to question 4, they won't have information about you if they have never received a game where you were one of the players.

True, but many of the beginner kids that have a profile dont have any games either. In fact, some of them have only played in 2 or 3 local tournaments.

I don't know but maybe someone they played is in the DB and the events they were in are loaded, even without games. Either way, questions about another site really are best asked through that site's contact methods.
