In order to block certain inbound traffic from going through to the offer's landing page, you can easily add blacklisted referrer domain on Advertiser level.
Any traffic source whose domain is listed, Converly will redirect the traffic to a not found page.
To add any blacklisted domain, please go to an Advertiser Detail page > System tab > Fill out Blacklisted Referer Domain TextArea.
Notes: You can also put partial words into the list. For example: entering 'sextoys' to the list will blacklist any domain containing the word 'sextoys', such as: sales.sextoys.com, sextoysrus.org, sextoysforsale.net.
