Don't most people consider repeatedly hitting the same target over and over "farming them" or "zeroing them" out. Thus, you are playing farmville by your choice of convient attacks.

Depend on how they got there. Usually we don't alert unless the alerted has been going at it for several rounds. Hackers can target a person on the tab with out them dropping off. So yeah if they take advantage of it, the we will return the favor. But on a personal level I would rather see the legion as a whole zero them out by hitting them once each. Now for those legions we are at war with that is another ball game.
