The 2 bundles where I saw people refusing to accept the bundle later had basically the following scenario: (i did not host them.)
The admin made a game jam where everyone could submit games to the bundle if they liked. It was stated that everything submitted will put into the bundle after a certain date. In both cases, people submitted their stuff to the game jam, then waited for the bundle host to create the bundle, waited that more than 50 percent accepted the bundle, and then publically stated they wanted to get out of the bundle. These persons had plenty of time to leave the bundle beforehand, but instead, they decided that they wanted to leave the bundle at the time when it would cause the most trouble for everyone else involved.
This is what I meant by "to annoy other people"
