Yes, they often do. An essay summary usually contains the main plot points, key characters, and important events of a novel. This can give away the overall story arc, major twists, and how the story ends, which might spoil the reading experience for someone who hasn't read the novel yet.
In the Bump World, contestants could give gifts to each other. The act of giving gifts was often seen as a social behavior that helped to strengthen the connection and friendship between contestants.
There were certain restrictions on gifting in the Convexed World. For example, contestants could only give gifts of the same type, and the value of the gifts could not exceed the contestant's current wealth. In addition, if a contestant accepted a gift, they would not be able to accept other gifts of the same type.

Wattpad also has a lot of fan - inspired content. It's a large writing community where users can find stories inspired by their favorite books, movies, etc., much like fanfiction. There are different genres and levels of writing quality, but it offers a wide range of reading options.
