The honest answer has two halves, and which half applies depends on whose post the comment is on.
Partly. Automatically replying to comments on your own posts is allowed, and Tadlo does it through Meta's official Instagram API. Automatically posting comments on other people's posts is against Instagram's terms and risks action blocks or a ban, especially with tools that need your password.

| Action | Allowed? | What decides it |
|---|---|---|
| Auto-reply to a comment on your own post | Yes | Official API, your own media, your own account. |
| DM the person who commented your keyword | Yes | Their comment is what permits the reply. |
| Hide or filter comments under your posts | Yes | Moderating your own comment section. |
| Auto-comment on other accounts' posts | No | Automated activity directed at accounts you do not own. |
| Mass liking or following to attract attention | No | The same rule, and the pattern most likely to trigger an action block. |
| Any tool that signs in with your password | No | No official authorisation, so Instagram sees your account behaving automatically. |
Because Meta publishes an interface for the first and not the second. The official Instagram API lets an app you authorise see comments on your own media and respond to them. There is no API for commenting on somebody else's post, so a tool that does it has to impersonate you in a browser session instead.
That is also why the risk sits with you. An authorised app is identifiable and rate-managed by Meta. A session driven by a bot is just your account behaving like software, which is what automated-behaviour detection is looking for.
Somebody comments a keyword under your Reel. The automation replies in the comments, sends them a DM with what they asked for, and optionally confirms they follow you first. Nothing touches an account other than yours, and every message is a response to something that person did.
Comment-to-DM automation is that workflow, comments management handles moderation under the same posts, and DM automation carries the conversation on afterwards.
Spotting the difference at signup: an official integration sends you to Instagram to authorise it and never asks for your password. A tool that wants the password typed into its own form is the other kind.
Official Instagram API, Instagram Login, no password and no scraping — so there is no ban risk from either. Replies are paced rather than fired in a burst, which keeps a post that suddenly performs looking like an account rather than a script. The free plan includes it; pricing covers the rest.
What actually gets accounts actioned, and what does not, is worked through case by case in Is Instagram DM automation safe?.
Not for replying to comments on your own posts through the official API — that is a supported use. The risk comes from automating activity on accounts you do not own, and from tools that need your Instagram password, both of which fall outside the API entirely.
A temporary restriction Instagram applies when an account's behaviour looks automated — commenting, liking or following stops working for a period. It is the usual first consequence of engagement-bot activity, and it arrives before anything more permanent.
Yes. Replying to comments under your own media is what the API exposes, so an authorised app can post a public reply as well as send a DM. What it cannot do is comment on a post belonging to somebody else.
Yes, through the official Instagram API, and it is one of the main things the messaging API exists for. The person's comment is what permits the message, which is why the pattern works without anyone cold-messaging a stranger.
Watch the signup. An official integration redirects you to Instagram or Facebook to authorise it, and the tool never sees your password. If it asks you to enter your Instagram username and password into its own form, it is not using the API.
Yes, when the check is a read of follow status through Meta's API rather than a trick. Tadlo reads it from the API, which also means existing followers are not asked to follow again — something an honour-system gate cannot tell.
