Yes, we can certainly help you with this.
When logged in to Fanball go to the top right corner of any screen and click on your personal widget that shows your picture. Click on the Settings tab then click on Self Exclusion.
Self Exclusion puts a complete halt on your playing. If you do not want a complete halt, you can impose Play Limits on your account. These limits cannot be loosened for 30 days (90 days if you are a resident of IN or MA).
