It seems like the vast majority of all brute force attacks to our server (well over 90%) and other unwanted scam/spam traffic comes from China, Mexico and Turkey.
Every day we blacklist their IPs but it's taking up lots of time and getting weary since it's a never-ending process what with 100s or 1000s of IPs potentially involved.
We asked our webhosting firm for instructions on how to block ALL traffic from the 3 nations but for some odd reason they ignore that question and instead say to continue blocking individual IPs.
There is little if any good reason anyone from those nations would want to visit our websites in the first place so we would not be losing quality traffic and legitimate business.
Can someone here tell us how to do it?
