@hailmori,
I see, so you've never published anything on Wattpad before, which is why it's natural to hesitate.
And about what you're saying regarding the warning before publishing, "I acknowledge this is my own original work, or I have the permission from the original author to post this work. Copyright infringement may result in story deletion or account closure." This warning is something that all Wattpad accounts get when publishing a book.
Let me tell you, many Wattpad authors, even if they don’t own the rights to a particular novel, still publish it, simply adding a disclaimer that it’s not their original work. Mostly, I’ve seen that if you give a disclaimer, your account doesn’t get reported by people, but in this case you need to remember that it must for just offline purpose!!
You must remember that using someone else's novel or book, even for offline purposes, comes with responsibility. If you're not trying to profit from it—like locking chapters or earning coins through Wattpad—then it's generally ok. Otherwise, it could lead to your account being flagged for copyright infringement.
As for the accounts you were following that got deleted, keep in mind that these accounts, which often publish non-original content, are at risk. Yet, many continue to post because they enjoy reading these books. Despite knowing the risks, they, as true readers, are willing to accept them.
Also, there's a possibility that the accounts you followed were deleted not due to reports but for other reasons—personal matters, or perhaps the creators simply chose to leave Wattpad. You never really know the full story behind it.
I hope this clears up any doubts and helps you make a more informed decision!
