[ DDoS ] Return 444 Instead 429

I wasted a lot of resources because of this!

Sorry, I don't understand why this is a waste of resources.

I suggest to use 444 response because it will not give any response to the attacker.

This is not DDOS, this is seven layers of defense, I guess it is good, he may not want to return the error page or response, so the server still has resource consumption. Especially when the attack is large.

If it is DDOS, it belongs to mandatory blocking and will not be approved by you. That is to belong to baleful flow, you do not have the leeway of resistance, you can increase defence to use bandwidth to clean only.
