I declined your flag.

Taking the flag on its own, without looking at the question (which is what happened in this case), the flag was about enforcing rules/TOS/EULA for another product/site/etc.

Stack Overflow moderators are not responsible for enforcing the agreements that another company has with any of it's members, just Stack Exchange.

It's the same reason that we decline iOS (insert version here) questions that are under NDA. It is not the responsibility of Stack Overflow moderators to enforce the agreements between two separate third parties.

That said, I declined the flag, because it's not up to me to determine whether or not a user is trying to so something Reddit doesn't approve of.

I probably should have chosen "flags should only be used for things that require a moderators attention"; this would have been more apt. Sorry for the confusion.

I did look at the question afterwards, and noticed that the question doesn't meet the standards for the site in general, and closed it on the spot.

It just so happened that the two actions were disjointed which is why you see a closure but the flag was declined. Note that the closure had nothing to do with what was being asked, but the quality of what was being asked.
