It depends on how the individual treats the account. People using that technique to massacre and humiliate are pretty annoying. They might severy sour the experience of someone genuinely new to the game and discourage them altogether. No one enjoys being hit over and over before even being able to understand the controllers enough to develop some finger memory and reflexes.
That said, not everyone that does that will be a jerk. Some people just feel like they didn't enjoy their first rounds and kind of want to have a proper beginning, some others just are looking for a less demanding environment.
I pretty much had to delete my file and start over in a game, so I did have the advantage of having more of a clue on what I was doing that my peers but for the most part it felt rewarding because they were picking up what I was dropping and I felt like a big brother, hehe.
On the other hand, I had some people thinking I was an easy target and chasing me a lot when I was within the first 10 levels. I liked to distract them with the chase and then try to dispatch them. They rarely saw it coming. they really low their guard when they think you are a newbie. Haha.
It was kind of bittersweet, to be honest, to think this is what many people genuinely new are experiencing in these games once it's been a while since the game has been out.
