My blog has been suffering a lot of spam since I set it up, and a lot of it comes from the same group of spammers! I checked my logs the other day and found a huge amout of refferal sites that spam originates from. So many that have somthing to do with online casinos, poker, etc… any way I have finally a installed a .htaccess solution to block these refferals so hopefully I will get less from now on… although I do have one concern, does anyone know if the is a bug speed hit for the work that htaccess does?
