Buat yang punya blog di domain sendiri (self hosted) alias tidak di penyedia blog seperti wordpress atau blogspot mungkin pernah mengalami beragam serangan spam.
Entah berupa serangan komentar (comments) atau bentuk-bentuk lainnya blog post (jika membuka blog untuk posting), email, dll.
Kebetulan. Gw sendiri pernah merasakan hal tersebut untuk situs gw yg lain, modelkit.org. Situs yang khusus untuk komunitas penggemar model kit Indonesia tersebut seringkali mendapat postingan yang dilakukan oleh software otomatis (bot) yang menghujani forum, blog, classifieds, atau kategori-kategori lain dengan sampah-sampah (spam).
Lucunya, kalau diperhatikan statistik dan log-nya, tindakan tersebut banyak dilakukan dari IP negara China!
Sebagai contoh; gambar disebelah menunjukan hasil penelusuran dari IP pendaftar atau pengguna situs yang melakukan spamming. Setelah ditelusuri, pengguna datang dari ISP Chinanet yang berlokasi di Beijing.
Dan itu memang hanya satu contoh saja. Tapi dari IP-IP yang lain terlihat bahwa pengguna memang banyak datang dari China.
Negara yang selama ini selalu memegang urutan teratas sebagai negara pelaku-pelaku spamming.
Untuk menghindari serangan lebih lanjut. Kita dapat melindungi situs kita dengan memblok trafik dari China.
Salah satu cara yang banyak digunakan adalah dengan memblok IP address yang digunakan oleh China.
Cara tersebut bisa dilakukan dengan memodifikasi file .htaccess yang terdapat pada root folder situs kita terinstall.
Silahkan edit file htaccess di root folder, dan masukan parameter sbb:
order allow,deny
allow from all
# China IP Address Blocks
