Why youtube is not deleting reported comment? ?

Reported multiple times. The comment is aggressive and sounds a threat if you read the conversation. But yet it is not being taken down.

The same reason reported posts here stay forever. Someone in authority doesn't care enough, doesn't have time, doesn't have enough reports to act, doesn't have a program that works as it should, or doesn't agree with your assessment.

Or maybe it sounds like an aggressive to YOU and not to others. YOU apparently are not the source authority.

You have less power than you think.
