MTurk - qualification requirements: exclude participants from pilots

[Jan]

Dear all,

I need to exclude MTurkers who have participated in my pilots from participating in the main experiment.

There are some guidelines (e.g. https://blog.mturk.com/tutorial-best-practices-for-managing-workers-in-follow-up-surveys-or-longitudinal-studies-4d0732a7319b).

But I couldn't find an explanation how to do this in oTree and what exactly to include in my qualification_requirements setting.

 Any help is highly appreciated :).

Thank you in advance and best
Jan
