I have been writing these rules to combine various version of words into one
rule. For example:
I start with
/prescription/
and do some minor subs to make
/pr[e3][s5]cr[i1]pt[i1][o0]n/i
Then, add gappies
/p.?r.?[e3].?[s5].?c.?r.?[i1].?p.?t.?[i1].?[o0].?n/i
(Side question, what's a good gap class, \A or [-_*/\. ], or... ?)
Is this a good rule? A better generic rule might be
obfuscatedmatch("prescription")
which processes the string with all the infamous tricks that spammers use
(i and 1, o and 0, a and @, gaps, etc.) Ideally, obfuscatedmatch would add
more weight than a regular match. Someone talking innocently about their home
mortgage won't spell it [EMAIL PROTECTED] :)
