is this sub legal??

Ever heard of something called a "stack exchange 'board'? on stack exchange you have forums for every topic, and you have "Stack Exchange 'boards", which are all the stack exchange subs categorized by topic, and if you sign up for stack exchange, you pick 10 Stack Exchange subs that you infinitely browse between. but you don't get one for shoplifting. I might post about this on the stack overflow blog.
