Yes, there is an illusion of fairness in having a black and white rule with an absolute threshold. However, I do not think such a standard is very wiki-like in spirit. In my case, because Netoholic saw fit to continue in pursuing punitive actions against me, even though there was no longer any disagreement between us, I feel very little good will towards him.
I note that there was little administrator support for continuing the block, once the situation was understood, regardless of Netoholic's many arguments that it should be continued/extended.
