commit 41ffd515a47f3254b1cc0ec4a563ed51508899a4
Author: Isis Lovecruft <isis at torproject.org>

    Add EMAIL_BLACKLIST and EMAIL_FUZZY_MATCH settings.
    
     * ADD the EMAIL_BLACKLIST setting, which is a list of blacklisted
       (spammer/harvester) email addresses.
    
     * ADD the EMAIL_FUZZY_MATCH setting, which allows for fuzzy matching of the
       EMAIL_BLACKLIST addresses via the Levenshtein Distance algorithm.
