I've just reached 20k and got the ability to vote to delete posts that are -1 or below.
I don't understand the purpose of this, or how I should be using it.
Currently, when I see an answer by a new user that is NAA, I flag as such and add a comment explaining where they've gone wrong and what they should do instead. Then, once a moderator comes along, the flag is seen and the answer is deleted.
Now, according to the privileges page, I should vote to delete when…
The answer doesn't attempt to answer the question; it may be a comment or a separate question altogether.
Therefore, as far as I know, I should be voting to delete such answers, which is fine. However, this means I have to downvote the answer — should I be doing this? I haven't been doing this before for new users' NAAs as I thought it'd put them off participating further, yet voting to delete requires the answer must be downvoted.
Also, should I be voting to delete instead of flagging as NAA, or as well as? Flags go into the flag queue which are immediately noticeable on the top bar, yet voting to delete goes to a relatively hidden part of the 10k tools. Do ♦︎ moderators see delete votes differently to how the 10k tools hides them?
Finally, taking a step back, what's the point of all this? There are currently 4 other users with 20k, one of which has binding votes anyway. It takes 3 delete votes to delete an answer, therefore it needs 3 of us to be online at some point, open the 10k tools, go to the pending deletion votes and take action, or be active in the Low Quality Post review queue all before one of the many excellent timely moderators swoops in and kills the post anyway.
