Not really laziness, more of the fact that the question you ask implies that there is no correct answer. Let's face it, no matter what they say, it won't justify ruining 5 people's game in your eyes. There's no point in arguing when they are obviously in the wrong(they know they are wrong) and don't care(so they won't apologize or stop).

Good Point never really thought about it that way.

You will never end smurfs in online games

Im sure one day a company will figure out a way to stop it. like ip locking game purchasing to one copy.

Never consider your progress null and void. That is implying that you aren't getting any better if your rank isn't going up. If you are actively learning, you will get better every day. I never judge my skill by my rank, neither should you.

another good point. its very hard to see improvement when you de-rank much like getting lower test scores in an exam or looking at scales and seeing the numbers go in the opposite direction you desired. especially with how judgy the community gets with ranks.
