Tolokers can be banned in two ways:

  1. By the requester.
  2. By the platform.

How to ban a Toloker

You can block a Toloker's access to one or more projects. This lets you control manually which Tolokers will complete tasks. For example, you can choose all Tolokers with a skill value lower than N and block their access to tasks. You can also unblock access.


The assignments submitted by banned Tolokers will be taken into account if they are not rejected using manual review. They can be reassigned by setting up the Recompletion of assignments from banned users rule.

In the interface
Via Toloka API

To block access to tasks for a single Toloker:

  1. Select a Toloker on the Tolokers page.

  2. Click Actions → Ban, then fill in the fields:

    Ban type

    Where to apply the ban:

    • In all my projects — All projects.
    • In the project — A single project (choose one from the list).
    Ban expiresSet when to lift the ban.

    We recommend blocking access temporarily in order to maintain the desired number of Tolokers for completing tasks.
    ReasonThe reason for banning (only seen by the requester).

To block access to tasks for multiple Tolokers:

  1. Select Tolokers by using the filters on the Tolokers page or upload a TSV file:

    <annotator id 1>
    <annotator id 2>
    <annotator id n>
  2. Click Ban, then fill in the fields (see the table above).

You can view information about access to tasks on the Toloker's page (on the Tolokers page, go to the Bans tab). To unblock access to tasks, hover over the ban line and click .

Banning on the platform

Toloka has dedicated anti-fraud system for banning dishonest Tolokers. It monitors user behavior and blocks suspicious accounts.

The main reasons for banning:

  1. Disclosure of confidential information.
  2. Using scripts and bots or any form of cheating.
  3. Poor response quality.
  4. Providing false data during registration.
  5. Frequently skipping captchas or entering them incorrectly.
  6. Using multiple accounts.
  7. Location cheating.

If a Toloker's behavior seems suspicious, write to support. We'll conduct an additional review. If the Toloker is violating the user agreement, they'll be blocked in the system and will no longer be able to complete tasks.

You can also ban this Toloker from your project.
