Merhaba,
Sitelerime gelen güncel botları içeren siteler yer almaktadır. Ek olarak RewriteCond üzerine eklediğiniz sitenin ardından SetEnvIfNoCase e'de eklemelisiniz.
Subdomain yada http ya da https girmenize gerek yoktur. Sadece site adresini girmeniz yeterlidir.
Sitelerimden birine spam göndererek test ettim. Sorunsuz ve etkili çalışmaktadır.
İsteyen kullanabilir.
