Nginx GET atack

Question

como posso bloquear este pedido methoh, porque eu consome todos os meus limites em vps, e o site se torna indisponível. Eu configurei mas ele não conta no nginx.conf

    map $request_method $limit {
    default         "";
    POST            $binary_remote_addr;
}

limit_req_zone $binary_remote_addr zone=perip:10m rate=1r/s;
limit_req_zone $server_name zone=perserver:10m rate=10r/s;

e no common_http.conf

if ($request_method !~ ^(GET|HEAD|POST)$ ) {
return 405;
}
try_files $uri $uri/ @backend;

pedido do nginx access.log
