You can control which type of users are completing your tasks. For instance, you can select users by region or assign tasks to users whose responses have passed quality control tests.
You can filter users by the following criteria:
Information in the profile, device characteristics (IP address, OS used, and so on), and the user rating in Toloka. To do this, set up filters in the pool.
Quality of task completion. You can filter out users who enter incorrect responses, often skip tasks, and so on. To do this, configure a quality control rule. To set up user selection using control tasks or the majority vote, you must create a skill. The skill is used for storing information about a user's correct responses.
Individually. You can block a user's access to one or more projects.
