Duplicated phone numbers in "bad_keyword.txt"

[iBug]

On Line 233, there's a pattern (?<=\+)234\d{8,14} that covers any phone number that starts with +234. Meanwhile, there are 9 other lines about individual phone numbers starting with 234 (no plus sign). I suggest removing the duplicated lines and remove the positive lookbehind for the plus sign on Line 233.

The dupe lines are 425, 461, 533, 549, 564, 571, 661, 937, 1007.

Line 233 modification proposal:

\+?234\W*\d{3}\W*\d{3}\W*\d{4,10}

As PR #1446 is merged already, this issue should be considered [status-completed].
