What could be the reason my account is suspended

1. The most common reason would be poor clicking accuracy.

if you try to surf too fast and click the wrong button several times

the system will automatically suspend your account.

To keep this from happening just slow down take your time and be sure to click 

the right image.

If images are not showing up you may need to change browsers.

Safari is the worst browser especially for ventrinos scripts.

Google chrome, and Firefox seems to work the best.

2. Your email could be bouncing due to a full inbox, Or an email the system doesn't like.

 yahoo and hotmail etc.

The best email to use would be gmail.

using bots,multiple accounts without permission.

cheating, or submitting a dispute to paypal or payza.

upgrading and asking for a refund without any good reason.

I hope this helps.
