Flag helpful, but post still completely visible?

Question

I flagged this question

We found a pattern in the random loss of balls in the popular US and European lotteries. For whom this phenomenon can be interesting?

as spam and the flag was considered to be helpful. Why is the post still completely visible including the video-link ?

Answer 1

My bad. I had just closed the question and did not go directly for deletion.

But with respect to the general aspect of the meta post, a flag can actually be marked helpful yet no visible and/or immediate moderator action be taken regarding it, or even some action can be taken which was not what the flagger had in mind.
