I'm not really making a big deal about it. I'm simply explaining to you things because you seem to be confused. :/ It's just that you're kinda not really listening to what I have to say (either that, or what I have to say isn't really getting across), so I'm trying to re-explain things as much as I can.
Well, that and I'm a bit worried here, if you don't mind me being frank. See, as I've said before, the reason why they brought up such a minor point (according to you) is because they're reviewing you. Folks around here do in-depth grammatical reviews, and they had a bit of constructive criticism to give to you. Sure, you might not have known that "ok" wasn't correct, but that's kinda the point. Because you didn't seem to know that, they pointed it out with the hopes that they could explain it to you in a respectful way so you don't make that same mistake again. You responded by poking fun at their reviews and saying they're criticizing minor and silly stuff, and that is borderline disrespectful and could be a problem when it comes to author-reviewer interactions on the forum. As you probably know from the rules, for the past couple of years, Serebii's been pretty big on the idea that both the reviewer and the author should be respectful towards each other. It's my job to ensure that's a thing that happens. So if a person is confused about a review, I do my best to help out, and if a person sounds like they're about to make things hella uncomfortable for a reviewer, then I step in and remind people about the whole respect thing.
Or in other words, it's the reviewers' job to point out things like that, and it's my job to ensure both sides are respectful towards each other during the exchange.
