plugin wasn't removed
I just made a mistake with permissions in code, then couldn't be assed to fix it and when I got into the mood of fixing it, I got sick and so couldn't test the fix for a day. When the plugin gets updated everyone who is an owner/member of the region they're in can use the command on a sign.
I had made the mistake of trusting a bunch of people in probably the top 100 most toxic minecraft communities to not abuse a feature. Don't fear, next plugin I release will assume every player on the server is a toddler and cannot be trusted with even the slightest bit of power.
