How do I report an issue?
Please fill out the form located at: city-data.com/bug-bounty-report.php
We need some time to process all requests, especially those addressing more complicated cases. Please allow a few weeks for analysis.
If we determine that a reported issue is valid and represents a security vulnerability previously unknown to us, we may issue a monetary reward between $250 and $3,000, depending on the severity of the vulnerability. We reserve the right to publish your handle or nickname if we issue a reward.
Residents of countries that are on U.S. sanctions or trade restrictions lists are ineligible to participate in the program. You are required to provide valid contact information and we will require your tax information if the payout is above $600. Any taxes due as a result of participation in the program are the sole responsibility of the participant.
If for any reason you are unable to or do not wish to accept a reward, you may donate it to a recognized charity (subject to approval). In this case, we will double bounty amount.
All award transactions will be completed through PayPal or check.
