The addon simply checks new buffs applied to your characters, scans for the sheep, shambler, love bug and fae morphs and instantly cancels it if it is found. It can optionally print who applied the buff instead.
Here are the slash commands:
/BBW will list all the commands.
/BBW on will cancel the morphs (this is the default setting).
/BBW print will print who cast this on you if a caster is identifiable, but leaves the buff on.
/BBW off turns off BBW so the morphs stick and you have no clue who cast it.
