or SPAM. How fast is the scan? URL scans are synchronous and complete in under 2 seconds. Each result includes first_submission_date (when the URL was first seen by the system) and times_submitted (how many times it has been scanned) — so you can tell whether a link is newly flagged or repeatedly reported.
