My reply: I can relate to this since my family runs a chain of stores in SoCal. We cannot deny anyone entrance into our properties UNLESS they are a repeat nuisance, but even then, we would have to file a police report, etc. etc. However, it is my understanding that the internet is a different playing field. It is our webspace, we pay for the domain and we maintain our website ourselves. That being said, I think I am as free as any webmaster to deny traffic from anyone/anywhere without due cause. I have no need to ever explain my actions, if I feel like banning someone, I'm within my rights to do so. After all, I am the one paying for the webhosting and everything right?
There is plenty of illicit activity in the continental US as well. I have a couple recurrent would be hijackers and content borrowers running an affiliate scheme that keeps hitting my brick and mortar sites from ft. lauderdale, FL and san jose CA. I ban them as I see them return They keep swapping service providers... probably their livelihood if you can call it that depends on finding the next way to take something that doesn't belong to them. No different really from taking any real property at least in effect. I had to take out a couple of canadian isp providers as well for the same reason. Probably just a handful of people, but they kept changing i.p.'s all within the same provders range. I also ban the i.p. ranges of the discount web hosts and cheap colocation facilities in the US. The biggest difference to me is the ISP's here will act... albeit when you make them. Whereas, providers overseas practically force my hand to ban their ranges as I come across them. Sometimes in doing consolidation and cleanup between the hosts.deny files apache config files and the firewall bans... I do just take out a particular class A. I think right now I have about 8 of them banned. We all have good and bad neighborhoods near the areas we live... and neighborhoods where we wouldn't want to invest in a business. No one has a problem with that being a personal decision... It's really the same with our websites.
