I dunno if that is only true for the EU server or only in non-Vet zones, but there is literally no spam anymore.
I have not seen a goldspam message in starter area /zone or gotten a Goldspam Mail in about a month.
The worst trolling attempt we had was a "this game is bad" a week ago. Everyone saw through it. Not even attempts of "use english in /zone on EU server".
I never bothered with a spamfilter addon. And I recently removed the last two lonely entires from my build-in ignore list, becuase they have either been banned or might have wised up a bit (in case they were trolls/really bad team players).
I fear you addon followed Batman Store Filter:
It was usefull for a time, now it is just not needed anymore.
That might change later. Just open it up for optional files/patches so we can later update it.
