Free fraud-check tools for sign-ups
These free fraud-check tools let you check a suspicious sign-up yourself, with no account: is the email address disposable, which inbox is behind a Gmail alias, and is the IP address a VPN, a Tor exit node or a datacenter? They run the same checks InlineShield runs on every sign-up it screens.

From one check to every sign-up
A tool is handy when one account looks odd. To check every new account, before it exists and before the bonus is paid, call InlineShield from your registration code with the REST API, or install the WordPress plugin. Each sign-up gets all of these checks at once, plus bot detection, and a clear answer: allow, allow without the bonus, hold for review, ask for KYC or block.
See every check on the features page. The Free plan includes 1,000 screenings a month.
