Technically anyone that has the "Toribash Staff" role is a Discord Moderator.
More specifically Help Squad members monitor and help in #support, answer any questions they can if they can at the time.
Now, I don't mean to sit and watch the discord the whole time but be more aware of what is happening with in that server. So people don't have to wait 30 mins for a fix to a problem that could prove simple.
If the problem is simple then the person with that problem could figure it out on their own no issue, if you're having problems with updates you will most likely be told to "Verify Integrity of Game Files" if you own the Steam version.
For standalone issues with recent updates you might be told to just delete the game and download it again to regain/fix files.
Help Squad (and a couple of helpful members) already monitor and help how they can, needing a dedicated set of moderators is redundant as all staff are basically moderators.
As MrMiyagy said
Waiting for an hour or two really isn't that long.
Just having a little patience can pay off, or simply trying to fix it yourself works too sometimes.
