Fraud Protection: Signups per IP

The Signups per IP setting is used to define the maximum number of signups that are allowed by visitors with the same IP address.

Recommendations

People sharing the same computer network will have the same IP address. For example, family members in the same home will have the same IP address, people surfing the web from the same coffeeshop will have the same IP address, and employees at the same company may have the same IP address.

If your end-users are primarily consumers surfing the web from their home or a coffeeshop, then we recommend setting the Signups per IP to a low value, such as 3.

If your end-users are primarily employees surfing the web from their office, then we recommend setting the Signups per IP to a higher value, depending on the number of employees at the company. If your audience is startups, then you may choose to set Referrals per IP to 10. If your audience is enterprises, then you may choose to set Signups per IP to 500.

Fraudulent Scenarios

Let's say you set the Signups per IP to 3 and a user (Jane) signs up and obtains a unique referral link. Jane attempts to cheat the referral system and move ahead in the waitlist by creating multiple fake referrals. She does this by copying her referral link and following it 5 times from different computers, phones, and tablets in her home. After each click she signs up with a different email address she owns. In this case, the first 3 signups will be allowed and the following 2 will be blocked. Jane will have successfully submitted the sign up form 3 times.
