Myth: tell people to 'DM me a word' to trigger the algorithm

Myth: tell people to 'DM me a word' to trigger the algorithm
DM volume is a weak, easily-faked signal the system discounts. n=170 accounts, A/B 4-week window.

— 'Comment a word for the DM' posts: +280% comments
— Non-follower reach delta: +2.1% (modest)
— Save rate on those posts: -1.1 points (engagement-bait fatigue)

The comment surge is reward-driven, not interest-driven, and 'not interested' rates rose 9%. So what: DM funnels work for list-building, not reach. The reach 'boost' is mostly the novelty of one post, not a durable lever.
