Would posting for getting minimum karma score to post be breaking TOS?

Hi, I am new here. I am trying to not break TOS here and want to also accrue Karma in the least spammy way possible. Please be patient with me if my question is novel in nature.

I plan to post in another subreddit where I frequently lurked for a long time and finally made a new account to post there. However, it has an age requirement and a minimum karma requirement. Would posting or commenting just to delete it later be considered spam or botting? Are there other mechanisms to acquiring karma outside of making posts and comments that I might be missing here IE upvoting others?
