If you are still seeing ads from advertisers you've blocked in Ezoic's Advertiser Blocker app, there are a few things to check.
First, you will want to ensure you entered the advertiser URL correctly. Note that you need to enter the root domain only i.e. ezoic.com for the 'Advertiser Blocker' app to work. www.ezoic.com or https://ezoic.com will not work.
If you use AdSense, I would also recommend also blocking those advertisers from within AdSense. Here is information on how to do that - https://support.google.com/adsense/answer/164657
If you are still seeing those advertisers being shown on your site once you've followed the above instructions, please reach out to your Ezoic account representative or the Support team to take a deeper look into this with you!
