There are logging limits in the app (https://joulebug.zendesk.com/hc/en-us/articles/360027736311-I-ve-hit-a-limit-on-an-Action-what-does-that-mean-). When these are exceeded a number of times during a challenge, the consequence is a timeout from logging in the challenge. Each time a limit is exceeded, the app provides messaging, as both popups and notifications. Timeouts start in small increments (15 minutes) and build from there.
We encourage you to log your actions throughout the day as you complete actions, if possible. You can also edit the quantity on each action to reflect your activity as opposed to logging the activity a number of times repetitively.
If you or another user are placed in a timeout during a Challenge your name may be greyed out and your score temporarily removed for the duration of the timeout.
