so i use my leisure to combined the "mixed version" to defend the spam.
I use the "Pierre's way" to do the first shield and the "nekobe's way" to do the last shield.
The "Pierre's way" can let me reduce to ban the spammer's IP.
I put the file here . if you need just to take it.
thanks to nekobe and Pierre first.
I just talk with Nekobe elder , he think a new way to defend the spam , but not to do it , he think bannimg the spammer's ip is enough to him.
Maybe this way is feasible.
