The endless stream of blatantly off-topic questions never ceases to flow into MSE, which is a topic that's been brought up many times. I've written a userscript that automatically casts a close vote, flags as VLQ, and adds a comment (if none already exists) or upvotes a comment.

Recently I got a VLQ flag declined for the following reason:

Using standard flags helps us prioritize problems and resolve them faster. Please familiarize yourself with the list of standard flags: see What is Flagging?

Meanwhile, the description of the VLQ flag says:

This question has severe formatting or content problems. This question is unlikely to be salvageable through editing, and might need to be removed.

What is wrong here? The inconsistency is particularly confusing that only one or two has been declined so far.
