Well, Is it just me or isn't that one of the major reasons why the discord channels and servers were provided or set up for each or most communities and tribes?
People drop by those servers to ask question about things they really don't seem to understand about a particular thing without having to create a post about it, which may look spammy like you said.

There are some subjects we want to know about and you never can tell,someone out there might have the knowledge about that particular subject.....

And about this, yes you are right. That is why the subject should be discussed by making or creating a post about it for others to learn as well.
