Heard: auto-DM tools vs 'comment a word' funnels — one is riskier than it looks

Heard: auto-DM tools vs 'comment a word' funnels — one is riskier than it looks
Confirmed: driving 'comment X and I'll DM you' generates reply volume, which feeds the reply-velocity signal.
Rumored: as of now, third-party auto-DM senders increasingly trip spam heuristics, and accounts running them at scale see reach throttling that looks like a shadowban but is automation-flagged behavior.
Use which when:
— Manual DM: small lists, low risk, builds the engagement signal cleanly
— Auto-DM tool: scale, but pace it under a few hundred a day and warm the account
What it means for your reach: the comment funnel helps the post; the auto-sender can hurt the account. Separate the two in your head.
