The key from my perspective would be to encourage undermining not specifically as a Strategic Goal for the Official Unofficial Community Leaders but as the more likely action than reinforcing for CMDR Jane Player who's just having fun getting merits, flying about, playing the game, etc. and has no expectation of getting into the top 10% on their power's leaderboard.
The Power you're pledged to should give rewards for successful undermining, maybe a much bigger version of the mini-care package?
