Looking at some of the news and discussion surrounding the game, it is clear that there are significant financial transactions involved.

The game is also four years old, well beyond the stage of mere interest checks.

It could be argued that the hack was carried out without a specific goal or knowledge of what data might be gained (as a display of hacking prowess, for instance). However, in this case, it’s clear why this particular game was targeted.

Whether or not the users “deserved” it is a separate discussion; one where I would agree with you. Many of the people involved may have been too trusting or gullible in their investments.
