Currently we only allow to show user IDs of users (in the future with OPT-2385 we will display the full names of the task workers or candidate groups). In many countries, it is not allowed to look at time spent on user tasks on such detail, but rather look at it anonymized.

Currently it is not possible to anonymized the data. Additionally, it is not possible to shorten the names and some of them can be very long and some users would prefer to use an alias.
