Instagram comment‑to‑DM automation: the limits you design around

Description and use

Automating replies to Instagram comments while respecting platform limits: rules, ceilings, and message queuing.

Problem

Automating replies to Instagram comments while respecting platform limits and preventing spam.

Outcome

The system delivers compliant automated replies, avoids spam detection, and maintains user engagement while respecting Instagram’s limits.

Workflow

• 1. User posts a comment containing a keyword (e.g., "price").
• 2. System matches keyword rule and queues a private reply (≤1000 bytes).
• 3. Public reply is selected from at least two variants and posted under the comment.
• 4. If hourly ceilings (60 public, 200 DM) are reached, the reply is queued for later within 7 days.
• 5. Replies are sent only within 24 hours of the last user message.
• 6. If the user is not a follower, a button is shown to request a follow before sending the material.
• 7. Keyword matches are case‑sensitive and win over AI rules; AI rules handle genuine questions with a separate hourly ceiling.

Evidence

A business cannot start a conversation in Instagram. Not by hand through a tool, not with a bot. The person starts it, with a direct message or with a comment.

Source

The private reply is a single message of up to 1000 bytes. In Russian or Kazakh that is about 500 letters, since Cyrillic takes two bytes per letter.

We require at least two variants for a public reply and rotate them.

Source

We keep our own ceilings per project: 60 public replies and 200 direct messages an hour.

Source

Once the person writes to you, you may answer for 24 hours after their last message.

Source

Owners ask for "send it only to followers". It works: instead of the text the person gets a button, a follower gets the material, a non‑follower gets a request to follow and a second button.
