Any point to reporting hackers?

I just got 2 shotted by a level 70 hunter. Normall, I'd not really care, but I'm a Death Knight, also 70, and while I am admittedly **** at PvP, I'm pretty sure that isn't kosher. Is this a problem that's being dealt with, or is it just so rampant that there's no point in even bringing it up?

Do you remember the name of that hunter? you can check his armory. Maybe he has full Epic gear equipped

You, most likely, ran into lvl 70 twink with good gear.
