I think whether or not it's a temp ban matters a bit here.
I never understood why "sniping" is such a big deal anyways, why can't a series get multiple interested translation group at the same time?
Sniping is a problem for several reasons
1) As I said in my earlier post, this hobby works best when groups cooperate and spread out to cover as much ground as possible. Every time there are multiple groups doubling up on a series that represents time that could've been spent on another manga that isn't getting a timely/accurate/good translation. And if you're a group that wants something to work on, why would you choose to work on something that's already being done instead of something that needs attention?
2) If there was no respect for territory and not overlapping the work of another group you'd end up with a lot of groups, especially the paywhore/money-beggar ones, just focusing on doing the most popular series to get the most eyeballs on their work and the greatest chance of earning money from people. What would suffer would be the less popular but still loved manga like this one that wouldn't get the same amount of attention
3) For a group that's translating it can be extremely demoralizing to have some others just drop in out of nowhere and start working on the series they do, especially if the new group does a worse job but releases faster/more chapters and the non-discerning part of the audience loudly goes "this translation is fine, it's totally readable and I don't care that it's not better". I have seen groups that have just up and quit working on a series because some trash-tier translator moved in and claim-jumped them with garbage output that people happily lapped up. That ends up depriving the people who
like quality work from getting manga done with attention and care instead of just being half-assed MTL/ai-redraw slop that reads like it's from someone who doesn't speak English and also has severe brain damage.
4) It's just basic decency. It costs nothing to be respectful of the work and effort of others and it's good karma/community-building to let people who are doing the job keep doing it while you find something else that fills a hole. That way everyone wins.
