I've only read the first page of comments so if what I'm about to say has already been spoken about, then just ignore this post.
I do get where you're coming from. There are too many people mini modding on the forums that every time I see someone trying to help, I literally think that they're a helper-wannabe even though it could be the person's first time helping someone else. I've seen it happen so much that I remember seeing in a thread where someone asked a question and then it was answered by 5 different people with the same exact answer.
The only way to fix the scenario that I just described would be to put a rule where if a question has already been answered correctly, the thread should be left for a staff member to lock or to just get lost between all the other threads. There's no need to answer a single question with 5 replies which are exactly the same.
EDIT:
Just to add onto this, I want to suggest to add another rule where users aren't allowed to post something useless for example "@staffmember, lock?". That in my opinion is message farming and I've even seen cases where people say it when they haven't even been part of the thread itself before that. The only people that should be allowed to request a lock is the person who created the thread itself.
