In addition to alerting your visitors when a browser extension is blocking AdFly, you can now decide to allow them to continue to the destination link or advise them to deactivate it for AdFly first.
Scroll down to 'Advert Preferences' and tick 'Yes' on the 'Stop Adblock Users' setting. Then click on 'Update Account'.
Users who now click on your AdFly short links will be requested to turn off any ad blocking extensions in order to continue to the destination website.
To allow them to continue anyway (earning no revenue) just tick the 'No' setting instead.
