Demotion - Sinistra/Fix Commands

Alright, so a kid in game did ::offpickup, well, HE was a normal player, so am I, so I decided to test that command, to see if it was admin/mod only. Come to find out it wasn't and as soon as I press enter, the co-owner says 'Don't Do That', well, it's kind of hard to undo a command; but I won't do it anymore (I have no problem with the co-owner). But then, I started explaining what this was, and Sinistra says "blah blah blah..and no it doesn't", and I say "I think I should know." Seeing as I have had a private server of my own. Well..I think it's abuse of his powers if he says 'Shut up or I'll ban you'. I was just trying to explain what it did? This needs to be looked into.

I didn't receive a ban from this.

P.S. If you need help fixing that command to where it's mod+ only, I'd be glad to help.
