can't block MFA site

Dear dp members before few days i block some MFA sites as ?: under adsense setup > filter ads > add url > save

But today i see those ads r appearing in my blog! am i missing something?

 

You used the competitive ad filter? Usually it can take up to 24 hours for the ads to stop appearing. Did you use the correct format to block the MFA site?

 

I block as : www.yourcompany.com

 

Use just yourcompany.com

 

let me try, but the format which i wrote is also written in adsense a/c under filter url tab?

Whats difference?

 

i use both formats but they r not working what i am missing?

 

are you sure you're blocking the right URL?

 

yes am sure coz its a parked domain

 

Using domain.com will block all the ads from that URL, it's the best choice

 

but for me its not working i contact adsense support team but not receiving reply ...

 

Try right-clicking the ad and copying the 'link location' to a text file and analyzing it to see exactly what host is being used... Some MFA sites link through a 3rd party etc... you need to filter that 3rd party host .. not the Ad host.... if that makes any sense?

Cheers ....
