Thanks for asking. I want to see more participation on Meta! :D I like people posting here, yes, even if they are complaints. Meta is not a Moderator-Announcement Board. It's one of the community tools to discuss about the Site and yes, also challenge some decisions. Not everything goes here, but questions like this one are good! :)
I'll kind of repeat what I said in the comments but I'd also like to add something more, now that I have the chance to write a full answer.
Regarding the specific question
While it's true that the OP didn't show any research effort in the question, I decided to leave the question. My thoughts are that in our case, unlike StackOverflow, questions about homeworks are different, they are kind of "harder". By this I mean that assignments in Linguistics are harder to understand because although Languages are quite definite systems (despite the general thinking), they are not as definite as code questions. So, it's not like asking for 1+1=2.
The user also just joined us. As you can see this is not only the OP's first question in Linguistics but also the user's first question across all the SE sites: he doesn't have the +100 given to you when you join second sites. Unless he decided not to associate accounts, of course. But given that he was new at least in our site, I think we could go easy on new users. Not only because they are just starting to understand how SE sites work (which are harder than regular forums), but also because if we just start scolding people and down-voting their questions, they will be scared away and we would lose a potential good user just for a single question.
While I'm glad to see that other users care about the rules and not just the "evil Mods" :D I think that in some cases we can close an eye and help beginners to make their way. I'm not saying they're justified to do anything. But in telling them what they should or shouldn't do, we could use a different approach.
Regarding the matter in general
I'd like to make it clear that my opinion is to keep homework questions and not ban them. Why ban a possible resource for more questions? They can still raise interesting points, and so I think we should keep them. That been said, I also think we need to set some minimum standards, to make sure we don't get "gimme teh codez" questions.
For example: Ask the OP to show some "tries". We don't care if they are totally wrong. We just want to see that the OP tried to do something so we can also help more effectively on the specific problems. And if it turns out that they didn't understand anything, then we could also explain the whole thing, but still encourage for research effort.
I don't know what other criteria we could use, but we can certainly discuss about this. I'm open to suggestions.
