If you are on the free plan you are limited to 150 profiles collected per day. If you are on the trial, you are limited to 500 per day and 1,000 for the trial period.
If you hit that cap you will receive an email or see this notice in the dashboard "Great news! You’ve collected 500 leads in 24 hours or less. To resume collection, please book a call with our team."
What Do To If You Hit Your Collection Limit
If you hit your daily cap, you'll want to connect with our support team to discuss your options. We can turn your script back on, however, the next time you hit your cap your account will be disabled again.
The best approach is to upgrade to RB2B Pro which has higher collection caps and the ability to leverage overages.
