Hi. When attempting to access the site today, I got an automated response from the server saying it was blocking certain IP addresses and mine was one of them I don't know if this was intentional or not, but thought I'd let you know.
I was connected via a 3 mobile modem (last time I successfully logged on using this was two days ago). My understanding of this network is that it has a small number of IP addresses which hundreds of users share at the same time. If one of them was mucking about on the site and you blocked their IP address, you may have unwittingly blocked a couple of hundred innocent users who were allocated the same IP address.
My IP address at the time was <IP> Not sure if Vodafone and other mobile broadband operators use the same system of sharing a handfull of addresses, but it might be worth checking if banning addresses.
This is not a complaint (love the site... avid reader, seldom post...) but FYI
