For many people, myself included, I think being the recipient of an unwarranted T-Bag is marginally annoying, but also makes me more invested in the game. Simply because I'll then go out of my way to try and show the bagger who's got the bigger space hoppers. Ultimately, this generally results in a mini rivaly within the game, which arguably makes it more enjoyable. That being said, I do agree with you, I never initiate the bag war, as it is quite juvenile and disrrspectful. Although im not above finishing it.
