How To Fix this message

I'm playing Horde, and every time I queue for a battleground, I keep getting this damn message constantly. I'm so sick of it. How can I fix this issue

Disable your addons and enable them one by one to find the culprit, then check its options for anything that whispers

Create an addon with this site: https://addon.bool.no/

Then add this to the code section:

local blockedWords = {
"You can only whisper to members of your alliance.",
}

that worked, thanks a lot!
