Came across a new one today and thought I'd ask the other moderations/community if they know what the rules are on cross posting tag descriptions. The reason I ask is this morning I was doing my review suggested edit tasks and I noticed a user had filled in some tag descriptions, upon checking them if they was duplicate I found they were but from Stack Overflow.
We have the option to reject these tag descriptions if they are duplicate (external source). Is SO or any other stack for that matter an external source? Should these be rejected or approved? Ive searched for help, I'm sure this has been asked elsewhere, if you know please kindly point me in the right direction.
