Lmao, I hate groups / translators that drop a series and then come running back the exact moment someone else picks it up. It's like a 1st grader pitching a fit some other kid picked up the toy he forgot about. Especially when they repost the chapter that was just done, doubly so when it's of equal, or even worse, lower quality.
You've only got an argument for sniping if you published in the last 3 months, at the most.
