I don't quite understand what part of various popular addons are showing group loot. I'd like to see users blocked from seeing what I pick up. Anyone know what specifically is allowing users to see items looted by the group?
Interesting. So this is server side? Is it possible to spam people with false data? That would be just as effective.
Actually, just using the word 'spam' should have made you think long and hard what you were trying to do. I'm pretty sure that would count as 'disruptive behavior' in the sense of Zenimax's TOS, and any player using such an AddOn risks facing an auto-kick by the servers or worse, a ban.
