I think it would be better to have a #help text chat on discord where you can ping staff instead, would be much easier to setup and could possibly help. And of course any misuse of this system would result in a discord ban.
You can /staff too get a staff to check it out quickly, and if no staff are online you can gather evidence and report them on the forums under "player reports". I don't think this suggestion would help or work all to well.
