Sometimes our campaigns go viral for the wrong reasons. Maybe a bot or another malware hits the button so many times that gets your campaign exploding.

But you only want the real referrals there, we've got you covered.

In Viral loops we strongly suggest that you always have the following enabled:

1) Double Opt-in, check here on how to implement this

2) reCaptcha verification.

reCaptcha introduces an invisible challenge that runs on the participant's computer upon registration. The challenge itself performs various checks looking for suspicious activity, a sketchy browsing environment - and more - eventually returning a thread score. We use that thread score, among other parameters, to derive if a participant is fraudulent before they even finish their registration.

Crucially, all of this is invisible, the participant won't have to spend time trying to find the squares containing a fire hydrant or a crosswalk.
