Why does a hacked solution display as Accepted?

Правка en2, от txingml, 2020-10-06 13:25:22

I want to learn a fast solution for

Bubble Cup 13 - Finals [Online Mirror, unrated, Div. 1] B Valuable Paper

https://codeforces.com/contest/1423

So I click here.

And sort all accepted solutions by Execution Time.

The fastest one is https://codeforces.com/contest/1423/submission/94770930.

I read it carefully and found it is wrong. Then I noticed that it already has been hacked. https://codeforces.com/contest/1423/hacks/669563

Why does a hacked solution display as Accepted? I think it can mislead users.
