wilderness... so was I! :) Some server farms are just icky and it is far easier to deal with a group ban than fiddle-pharting with narrow ranges. Most of my ip bans are either nnn or nnn.nnn I think I might have two which are nnn.nnn.nnn
Should traffic (human) fall off, I can always undo any of those ranges or fine-tune them, but for the most part I haven't had to do that. Again, pick and choose which battles. What works for me may not work for any one else.
