Damnspam improvement

I had a thought of something wich would be really usefull in big builds. The thing i had in mind was a command like /damnspam whitelist (player name here), or as an allias /ds wl Name. I think this would be very cool, since you could use this for demonstrating things. This would also be usefull when testing a layout, because when somebody who doesnt know tries it and breaks it, you’d have to redo the whole setup, this is basicly my reasoning on why i find this a very good idea.
