Because it allows you to rapidly inform yourself about what caused the unusual pattern in the reviews. As they explain in their blog post.Why even include that second option unless you want to encourage and facilitate this behaviour? Why?
Exactly.This seems like a great feature.
Users now see that there was a review bomb. Users can then read reviews specifically from that period to see what was going on. Users can then decide how much weight to give to the bombers.
Review bomb occurs due to something completely unrelated to the game? Users can ignore/exclude it.
Review bomb occurs due to something "terrible" happening to the game? (Features removed, awful support, devs abandoned it in unfinished state, etc) Well great, now users can see that the review bombing is actually very relevant to the product!
So basically, I don't think this feature "empowers" bombers. It empowers users, who can now choose to empower bombers.
Now this is an issue that should be fixed -- the algorithm apparently isn't smart enough at determining what an unusually high volume constitutes in cases like this one.What the heck?
