IP data is cached for 24 hours. Your account is not charged duplicate credits for any duplicate calls within a 24 hour period.
On the Advanced Reports page on the user dashboard it is possible to export IPs in certain fraud score ranges, which can then be made into a unique list for blacklisting on a firewall.
Hi lovesamla,
If your account was restricted as a duplicate account, please contact us so we can restore the full features. Due to frequent abuse we need to limit free accounts to 1 per person. We’re happy to assist anytime.
Thanks,
