Really weird how it took another TL dropping a chapter for you to instantly drop yours.
Let's take a look at upload dates for FranscurryTL:
Chapter 71: 11/1/2023 (6:54pm)
Chapter 72: 12/7/2023
Chapter 73: 1/21/2024
Chapter 74: 3/16/2024
Chapter 75: 3/16/2024
Now let's look at the upload dates for LHTranslation:
Chapter 71: 11/1/2023 (12:30pm)
Chapter 72: 12/6/2023
Chapter 73: 1/16/2024
Chapter 74: 2/8/2024
Chapter 75: 3/17/2024
Historically, it's usually LHTranslation that uploads its translation to MangaDex first, then FranscurryTL uploads its translation soon after, so whatever you're accusing LHTranslation of, all of the evidence suggests that FranscurryTL is the one that's actually guilty.
Or maybe they both start trying to translate new chapters as soon as the raws come out, and since they both get the raws at the same time, there's nothing suspicious about both translators finishing around the same time, regardless of who finishes first.
