It isn’t really reasonable to expect us to sit there and try to go through each and report them when they are up. As I’ve been seeing lately a lot of these bots have 1-2 live players guarding them, or a zerg from your team mows them over before you get the chance.
In WvW you can’t click on them after they are fully defeated, so I’ve run into many instances where obvious bot groups have gone unreported because of this.
