RadiantRay

But I didn't have the duplicate spam filter on. Also the people it was blocking didn't have any of the keywords listed on the addon, and some of the guys wasn't even spamming or have said anything for the past 10 mins. One guy was trying to ask me a question and couldn't so i had to relog to disable the addon lol

That addon seems to be blocking people's messages for no reason. (I turned on the setting to show me the blocked messages but in greyed text) Realized 90% of what it was blocking was just normal chat. So i uninstalled it right after
