Oli,

regex is simply a more powerful notation vs. "plain english" for
specifying ban words. I believe the ban words list would be 4-5 times
bigger if regex is not used, and it would be harder to maintain.

The power is there to use or not IMHO. The degree of
"agressiveness" (which creates more false negatives) is decided by
the admin.
