People pretending to contribute in activities. Example: getting in a safe location and firing off a few shots at a time every now and then in strikes, waiting for others to clear out all the waves of enemies in the queen's bounties and finally jumping in and killing the boss (majority of those jerks were gjallarhorn users from my observation). Slowly making their way through strikes only to leave as soon as we get to a more difficult area. The list goes on. You're not fooling anyone, you lazy r3tards.. At least make it less obvious. Just know that I send at least 10 reports of your sh!t every time I encounter this. You want the reward but don't want to work for it. If you know you're that way, do those who care to contribute a favor and leave. The reports will flood Bungie from my end. And one day you'll be dealt with.
