From your Manage Ads Dashboard click:
"Hide Ad" - if you want your ad to stop showing for a short period of time
"Pause Ad" - if you want your ad to stop showing from 1 day - 6 weeks. The best bit? You won't lose anytime paid for (but remember that you can only pause your ad once every 2 months)
"Cancel Ad" - if you want to cancel your ad subscription (your ad will continue showing for the remainder of the period you've paid for)
"Delete Ad"- if you want to immediately cancel your ad subscription AND delete your ad from your Naughtyads account
Please see the screenshot below on where to find these options on your Dashboard. If you have further questions about managing your ad, please email us.
