About NSFW Mark

I would like to know the clear reason why it is marked NSFW, not a millimeter of underwear, not violent, and why it is marked NSFW.
I would also like to know why it remains impossible to post in contests, etc., even if the mark is removed due to an allegation.
I would also like to know why, after much effort with support, I am able to post, but when I do post, it is filtered out of view of other users.
To be honest, I believe that there are more than a few users who are disgusted by this and quit, and I would like to know clearly what the management thinks about this and what measures they are taking.
At the very least, if the results of the complaints were known, the users would be able to avoid this problem, but as it is now, it is unclear what is wrong, and I feel that it is even unreasonable.
The result of the complaint is too late, and the application deadline has expired, and they say they have removed the mark?
At the very least, please add a function that allows us to see what was caught by the regulation.
If there are any users who know why this attached video was marked, please tell us.
