Badboy doesn't seem to handle multiple/fast spam so well... Had like 3 gold spammers spamming almost the same thing two times each within a few seconds of each other in say, BB only reported 2 of them and 4 of the 6 lines got thru (or I'm assuming there were 6 lines and that the 2 reports were two additional lines). I can't seem to find the actual incident in my chat logs to post exactly what happened...
BadBoy handles upper/lowercase and spaces, so infact there's 2 triggers there that didn't hit, was the addon definitely on and updated?
Yes, it was on and updated.
EDIT: Err... forget it. Seems Answering Machine Pro sometimes plays back tells that were actually blocked by BadBoy. The original message was reported by your addon and never displayed in game. It doesn't happen all the time tho, so there might still be a bug.
