Every time someone joins the battleground instance, this message appears in the chat log. I'm assuming it has something to do with the announcement mechanism of this addon.

you assuming it wrong

I am also getting these messages about every ~10 seconds while in battlegrounds. If I disable honorspy the spam heavily reduces (probably some other addon having the same issue). Running version 1.6.7 too.

Edit: only on entering bg now, spam was with 1.6.6
