you appreciate that
A = 100%
aA = 50%
so a single capital letter could be enough provided its accompanied by few enough lowercase characters
Though I have typed at this post, my feeling is scripts are NOT a good replacement for a good Op. With this sort of script and some others that are "protection" you are more likely to have false positive results than being a truely useful script. Your example is a pefect one to illustrate that.
I can't think of how many times I have seen some op banning/kicking people and saying "It wasn't me it was my l33t script".
I'll stop here before I start a full on rant
