first, if he just wanted to practice he could have chosen some random series and start from the beginning. Secondly, he's the one who posted it on mangadex, not some other people.
In his defense, I likely wouldn't have "just chosen some random series" myself if I were practicing. Why pick a series in which I have no passion for, and potentially get the hopes of an entire fanbase up for a series I don't intend to continue and am just using to practice?
Picking a series which:
[ol]1. Already has a dedicated scanlation group for it, so I won't have to do it forever[/ol]
[ol]2. Is of a series I actually like[/ol]
That actually makes a lot of sense from the "practicing" perspective.
Yes, I'd piss some people off in the meantime. But I wouldn't have the baggage of a potential long term commitment, and would have valid reason to want to do it due to my liking of the series.
Also
It's group sniping because he put in chapter 39 instead of 1-39.
THAT would be unquestionably sniping. That would be showing the intent to a group that:
[ol]1. You're passionate about the project[/ol]
[ol]2. You're dedicated to the project[/ol]
Starting from the literal beginning of a series and going beyond the scanlation group would basically be a declaration of war.
