Rejected tasks

  1. Overview
  2. Request body

Overview

You can block access to tasks for users whose responses were rejected by the requester during non-automatic acceptance. To do this, set key values in the quality_control.configs array in the pool settings.

Request body

Access to tasks is blocked if 40% of the tasks completed were rejected by the requester. This condition is checked for the first time after 10 tasks have been completed.

You can ban a performer from your project for a given number of days, hours, minutes (at a time or in total) or permanently.

Ban for 10 days
