Blocklist
If you want to block a participant from participating in your panel/studies, you can now add them to the Blocklist. This will flag the participant in question, and prevent that participant from being messaged or completing screeners.
When a participant is added to the blocklist, you will notice this in two areas. The first is the Blocklist panel property:
The second is on the panelist message tab:
Additionally, the panelist will not be notified that they are blocklisted. This is to prevent the panelist from knowing that their account cannot complete screeners.
If a panelist has incorrectly been assigned to the Blocklist, you can set the blocklist panel property to False, and the participant can complete screeners and be messaged as before.
