  * Traditional word filters. Expires 31-12-2021.
  *
  * So, there are too flags at the end of each regex pattern, the "im" at the end. Case Insensitive and Multiline
  * let's take the third one as an example.
  *
- * n+ [^a-z]* [il1|]+ [^a-z]* g+ [^a-z]* g+
+ * n+ [^a-z]* i+ [^a-z]* g+ [^a-z]* g+  ( [$x_alias] is just a set of common lookalike characters for x)
  *
  * Basic regex syntax: * means the preceeding element will be matched if it repeats 0 or more times. + will match 1 or more times
- *
  * so a+ matches cat or caaat
+ *
  * [] denotes a set of possible matches, so c[au]t matches 'cat' and 'cut'
- * if the first character in the set is ^, that inverts, so [^a-z] means any character that isn't in the alphabet
- * (we have the case insensitive flag so captials are included)
+ * [a-z] means any character from a to z and [^a-z] means any character that isn't in the alphabet (the starting ^ inverts the set)
+ * We have the case insensitive flag so captials are included.
  *
- * so the [^a-z]* means that if someone does 'n..i..g..g', then the 0 or more non-alphabet
+ * The [$n_alias]+ means that nnnnnnigg still matches due to repetition
+ * The [^a-z]* means that if someone does 'n..i..g..g', then the 0 or more non-alphabet padding
  * 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.
  *
  * Example:
