Rules

What the policy asks of you, and the bug types it won't reward, quoted from Foursquare's policy. "We" in these lines means the program, not this site.

While testing

  • Respect our user’s privacy.
  • You may not access or modify user data without our permission.
  • Do not employ denial-of-service attacks against Foursquare, and attempt to avoid degrading our quality of service.
  • After reporting a vulnerability, we ask that you allow us a reasonable period of time to investigate and fix the issue before you disclose it publicly.
