Thanks Lucy24 with my limited knowledge of coding I implemented a solution similar to what you recommended. I renamed all the 3 pages so humans can see the links when they browse the site. All the zombie traffic seem to be programmed to go the the pages with their old names. So I use a 301 redirect to dump all this zombie traffic on a 4 octets or so txt file that says "Oops you arrived at the wrong place".
So it is helping me to save my bandwidth. Yesterday consumption was 650 MB (A normal day will be around 615 MB , a full day under non-stop can cost me as high as 15.47 GB like Feb. 7), I think I will go further down as I implemented this solution late yesterday at 7 AM after several hours of zombies visit.
I also signed up for Cloudfare. I'm not sure how this service work and how effective it is. But it says that it saved me 97 MB.
According to Cloudfare all my zombie traffic is USA based. I checked the raw log files they are from the US and mostly from consumer-based ISPs at the exception of two IPs which I blocked through .htacess as they are hitting me 600 times a day. These 2 are probably spammers.
I will go again today through the raw files to check for patterns in the IPs.
