There is a table “banned_addons” in characters DB but I never get it working.
No matter what I put the name of the addon in Name field (exact spelling, lower/upper cases, from folder name or the Title in toc file), Version (v5.0.1 or 5.0.1, whatever), I never get client addon banned after logged in. I also played around with Timestamp (like current, the past 2009, or future time 2020) but still, nothing worked.
I also dig into AddonMgr.cpp, WorldSession.cpp and confirmed the BannedAddonList did sent to client.
Does anyone know how to use this banned_addons? By the way I am using 3.3.5 branch and the latest commit 94f186e
