// Traditional word filters. Expires 31-12-2021.

// let's take the third one as an example. n+ [^a-z]* [il1|]+ [^a-z]* g+ [^a-z]* g+
// Basic regex syntax: * means the preceeding element will be matched if it repeats 0 or more times. + will match 1 or more times
// so a+ matches cat or caaat
// [] denotes a set of possible matches, so c[au]t matches 'cat' and 'cut'
// if the first character in the set is ^, that inverts, so [^a-z] means any character that isn't in the alphabet
// (we have the case insensitive flag so captials are included)
// so the [^a-z]* means that if someone does 'n..i..g..g', then the 0 or more non-alphabet
// characters between the n, i, g, g are still matching. Note that it's 0 or more, not 1 or more, so 'nigg' still matches.
// the [il1|] set is just common replacement characters for i that will be used in evasion. I'll add accents later.
