That's a joke! What f[size=2]eatures are exclusive for mods and admins in real world? [/size]
Real-world mods and admins? One example is turning back time when a disaster occurs. For example, April 10, 2016 would have had a 9/11-like event on DC's buildings if admins didn't turn back time and let time run its course in a different way (there's always random variation when you redo a day). The reason 9/11 itself wasn't prevented was because there was also a hurricane headed for NYC that day, and there was miscommunication between different groups of admins regarding 9/11 and the Hurricane Deflection Team, plus restarting the day 20+ times never got rid of 9/11 entirely but only changed its severity.
Admins can theoretically erase someone from existence, but it almost never gets done because the admin's approval rating will take a hit.
Santa would not be able to deliver billions of gifts in 24 hours (due to time zones) without the help of real-world admins.
