You can always deactivate the consumer/leads access to the customer portal by doing the following:
1. Login to ScoreCEO
2. Click on Lead/Consumers
3. Search for your Lead/Consumer
4. When you are on your lead and you are seeing there personal information. If you look below you will see a "Active Box"
5. Uncheck the box.
6. Click update

Or instead of unchecking the active button just click on the canceled button, this will stop all emails, campaigns, everything for this lead or customer.
