I'm the editor of this. I will add, however that mostly speculative, there's one anon who seems to have a personal grudge against GoggledAnon with a very similar way of posting and I suspect them being the same person as the one you replied to (they made a similar post last year, check their profile).
As for the MTL accusations, they are wrong as far as I know. I have no evidence backing up my claim, but also none against it. I've been working with Goggled's scripts for quite a while now, and they do still occasionally make mistakes just like any other human would, they don't seem like the mistakes a machine translation could make.
Even the text hook accusation isn't that bad. I'm not great at Kanji myself so I also use Kanji Tomo to find identify ones I don't know so I can look them up faster.
Anyway, you're probably better off just ignoring them and enjoying the manga if you like it.
