# twitterbot

> A Twitter bot is a type of bot software that controls a Twitter account via the Twitter API. The bot software may autonomously perform actions such as tweeting, re-tweeting, liking, following, unfollowing, or direct messaging other accounts.

## At a glance

- Operator: unknown
- Type: Preview

The [bot directory page for twitterbot](https://www.centinelanalytica.com/bots/twitterbot) has its robots.txt token and the steps to verify a request from it.

## How Centinel checks it

- **User agent**: The request calls itself this crawler. Anyone can send the same string.
- **IP ranges**: The operator publishes the addresses it crawls from, and Centinel checks the client address against that list.

A request that passes one of these checks is twitterbot itself. One that only matches the user agent is reported as unverified. The match tokens, verification domains, and address feeds are not published here.

## Allowing or blocking it

The [crawler object](https://docs.centinelanalytica.com/api/crawlers.md) in the `/validate` response sets `access_allowed` to `true` only for a verified source that your tenant allowlists. A [policy rule](https://docs.centinelanalytica.com/admin/policy.md) can allow or block this crawler by its category, `Preview`.
