Comment:

 So, I've implemented this ''slightly'' differently than proposed.

 Right now, there is a `EMAIL_BLACKLIST` option in the `bridgedb.conf`
 config file. There is also another setting, `EMAIL_FUZZY_MATCH` which
 takes an integer for the ''maximum'' Levenshtein String Distance for an
 email address to be considered as "fuzzy-matching" one of the addresses in
 the blacklist. These things currently are quite simple, i.e. they have no
 mechanisms for learning, and email addresses must be added to the
 `EMAIL_BLACKLIST` list by hand.

 My work is in my `fix/9385-fuzzy-email-matching`
 [https://gitweb.torproject.org/user/isis/bridgedb.git/shortlog/refs/heads/fix/9385
 -fuzzy-email-matching branch], and there are some added unittests, [https
 ://travis-ci.org/isislovecruft/bridgedb/builds/29335058 all of which are
 passing].

 I would like to merge this into `bridgedb-0.2.2`, so please review!
 Thanks!
