Hi Quintum!
I've been playing parkour for a little bit now and I'll agree that the chat can sometimes be an issue for those who don't already have it turned off! I do see the advantages of making the server appear to be constantly moderated, and I do think should this be implemented would make players who intend to troll chat think twice before starting and I can see some other benefits as well.
That being said the main problem I have with this idea is that it would just be confusing. I think the idea of making the mod tag red is a good approach to causing less confusion, however I see the possibility of new players who want help are going to be messaging these non-staff players for staff-related reasons. People who received the tag would also be able to easily exploit this to troll other players as well, and while I'm not suggesting that anyone would of course, the possibility would exist.
I personally think that a more permanent solution would be simply to have more staff for the server, as the parkour server does appear to be still growing as seen by the increased player limit. While there is potential in having false staff tags, even with the false colour I can still see this causing issues, but either way I think the idea is pretty smart!
These are just my thoughts! A thread like this probably belongs in the suggestions section since it's more of a suggestion as opposed to discussion. Also If you havn't already you can add your submission on

Thanks for reading, and have a great day,
