You don't seem to get the issue at all. I am not criticising "sniping". Imo when a manga has not been updated in a long time and is a ton of chapters behind native releases, it isn't even sniping. There is no need to sneakily ""steal/kill"" a project, when it is lying dead on your doorstep.
But translating chapters, that basically no one can use, is just an a***hole move. Like holding candy repeatedly in front of child and pulling it back, whenever the child tries to grab it. Who in their right mind reads the first few chapters, skips about as many as he has just read, read one and then go slowly back to the skip?!
At the current pace it will be another 3 months until we may be able to read chapter 10, which was translated around a month ago. Holding a carrot in front of people's faces for 4 months is just pure cruelty.
