We've implemented a feature that should make it easier for everyone to deal with reports of unauthorized code.
An author who finds a script that is an unauthorized copy of their own script posted to Greasy Fork can now submit a report from the bottom of the Feedback page. When this is done, the author of the offending script will be notified and allowed to submit a reply. The original author will receive notification of any reply.
A moderator will then review the evidence and decide whether the script will be deleted or the report will be dismissed, and both parties will be notified.
Eventually this may become automated in that if there is no reply in a specified number of days, then the script will be deleted automatically.
