I’m old enough to remember when Wikipedia was not allowed to be cited in high school papers because it wasn’t a sufficiently authoritative source. How the turn tables…
As an example, there is an American author B.B.Alston whose popular books for children were translated into dozen languages.
He has a page on Polish Wikipedia: https://pl.wikipedia.org/wiki/B.B._Alston
But my attempts to make him a page on English Wikipedia keep getting rejected -- failed to establish notability. The fact that he won some awards and kids read his stories on the other side of the planet is apparently not good enough for Wikipedia.
Looks like your drafts didn't have much in the way of sources. Someone else did a complete rewrite in September with additional sources to establish notability.
