Another (former) moderator and I both suggested this back in 2015 in the moderator section but never heard back from it. We all understand that Merkz is not comfortable with moderators using /vanish, so why not use /invis? People can still message the moderators and tp to them. The only difference is now ''hackers'' or rule offenders won't see them being watched. Will look for a plugin or ask my college friend to code one if it doesn't exist.
Support, /vanish could be better as it shows the Moderator isn't online but /staff overrules that in a few ways. Good Luck ;)
I used to moderate a server that had a command that would make it so you were in god mode, invisible, couldn't open chests, and you couldn't pick anything up. I'd love to see a command like this, support.
Support if Cyp and Noob find that the applicant is valid of being a moderator, there should be no worries of abuse.
