Yeah people do this simply don't recognize that they are annoying other people. From long time ago I have figured that there are two kinds of people in this world. One is more aware to him/herself and one if more aware to the outward world. Group 1 are usually tagging other people for their benefits (or, for the team's benefit as they so see it) while Group 2 do not do that very often. Of course this has nothing to say with selfishness or else. It's simply that each Group project their own ideas to the outward world -- so people who like to outreach think other people like that too, while people who doesn't think the inverse. But taking a step back as a third party, we would realize that Group 2 is usually more harmed than benefited.
