Just because you CAN do something dosen't mean you SHOULD. Like I have seen people spam #java with answering people's questions, and have the answers were false or made no sense, so really encouraging this behavior is not a good thing at all.
It can still be answered by staff, it's nice if a player wants to help but if they truly want to help, DM the user as I said, it has no place in any channel on the discord. It's not 2 sided because there barely is a positive side. The help you might get isn't confirmed, people can troll, could be misleading or confusing when messaged many times by different people, plus with Cuebcraft looking to have 100 active staff, this will be less of a problem.
