And by the way, if I were smiley and, in a parallel universe, I decided I wanted to publish to mangadex, I'd be upset too. You don't just dump 30+ chapters of a series all at once! For many different reasons, people drop series when that happens because you're giving them homework, so they put it off and eventually lose interest. Personally I think the best release schedule if you have the backlog to do it is one chapter per day if you want maximum engagement. So that's another dimension to this.
PS. I didn't say this anywhere else, so I'll throw it here: it is a minor point, but the uploader didn't even bother categorizing the volumes properly.
