Now, here's the real story. This clickbait article doesn't tell you the inside on GoodNovel and LetterLux that: The Trap: Their contracts are notoriously aggressive.

Rights Grabs: Some contracts attempt to claim copyright for the author’s life plus 70 years.

Future Works: Clauses have been found that claim rights to future books you haven't even written yet.

Termination: extremely difficult to get out of. Once you sign, that book belongs to them.

The Grind: If you stop writing daily, their algorithm buries you.

This story is trash and poorly written. The information within doesn't tell you the poison of those platforms. Beware and not so eager to buy into the hooks you see.
