Allow Second Life.
With the growing popularity of using virtual worlds to connect, teach and communicate, Second Life really should be allowed.
Not all of SL is "mature". There are universities present, corporations with "campuses", virtual concerts and charity events. Today, one of the book clubs interviewed Larry Niven, who was in-world, in full avatar as one of his own characters.
Give it some thought.
Still no huh?
Are you guys even thinking about it?
Y'all, I want to show people how I built a mid-century house to scale. No **** dungeon, I promise.
