Gần đây website của chúng tôi mỗi ngày có hàng trăm bình luận spam bằng các thứ tiếng nước ngoài, đặc biệt là tiếng Nga.
Cùng với đó là lượng truy cập tăng và CPU luôn trong tình trạng 100% gây lỗi 503 rất khó chịu.
Có nhiều cách để chặn các bot spam nước ngoài đó như dùng plug in, dùng cloudflare… Nhưng có một cách rất đơn giản là bạn hãy chặn các IP spam bot đó bằng cách thêm lệnh chặn truy cập từ các IP đó vào tệp .htaccess trong thư mục gốc của website.
Dưới đây là danh sách các ip spam bot mà chúng tôi đã tổng hợp, bạn có thể sử dụng luôn mà không cần lọc thủ công:
