<CampaignArbiter> "Hello there adventurer! You have two choices today. You can either go and fight those mobs for maybe 2k xp per hour, and run the risk of getting raped in the face by my happy friend Rojgnoj, or you can stand here and sing to me for 4.5k xp per hour."
<Adventurer> "Dah, dah dah dah dah daaaaaah! Dah dah dah dee dah dee doww"
<CampaignArbiter> "Ah I love me some dahs! Here, have another tag!"
Seriously, if some dude said to you "hey you could work in the mines for 5$ an hour or you can sing to me for 10$ an hour" which would you choose?
As for helping "the cause", someone who spams /brd songs and does the Campaign Ops that their nation actually needs is doing a hell of a lot more for their nation than the person that fights every campaign and only does Aegis Scream IV. See those stars behind the Campaign Op? Those aren't just happy-smiley stars. Those are an indicator of what's important. The only reason we don't have "omg fuck all you Aegis Screamers" threads is because it's impossible to see who chooses what Campaign Op.
