I have limited the dynamic/static request limit per IP, but I'm still getting hits from this IP, I also managed to place the IP in not allowed IP lists in LiteSpeed.

However, is it possible to do this thing automatically, because this usually causes a downtime and the time we intervein...

Thank you,
Hamza
