Honestly this is very sad. This has already been recommended but just make sure you check the ban history, have them send gfx of something you want them to do which exact directions, a gani with an exact image you want, a script which thought out directions (This one is important because with scripting you need more folder rights than others), and a sound effect of what you want. This will hopefully stop people from copyrighting files from other servers and will show you who is actually legit in their position. When the person starts to flake out meaning they will make excuses or say they are busy that is when you know they are just trying to be staff for the fun of it or do not even do what they say they do. Do not give anyone in a dev server ban rights. Make a jail level with a script which will prevent players from unsticking themselves and will serverwarp them to login each time they enter the server if they are jailed. This will prevent corrupt people such as Bella in this incident from banning other staff. Do not give staff powers they should not need and if they give you stink about it just let them leave or remove them because it is your server and your choices.
