Welcome to WebmasterWorld Guest from 22.214.171.124
they are trying to sell advertising on my sites, without my knowledge or permission.
However, the domain registrant who pays the web hosting fees and other website expenses, should be correctly identified by the ad network as he/she/they are the owners of the website, entitled to advertising revenue.Maybe I'm still missing, but if the ads are showing on your site- you are getting the associated revenue from the network. If the ad network is not paying revenue according to the sites where the ads actually show, then it's definitely time to drop that network!
unfortunately you fail to understand the problem.Um, perhaps because you didn't explain the problem properly? :)
scammer pays nothing and earns money from the ad network by hacking into my website and adding his/her code.You never mentioned anything about being hacked before this. That's a completely different issue.
Unfortunately, the ad networks are refusing to reveal the identity of the scammers so that legal action can be taken.
Why are the ad networks so keen to protect the identity of the scammer?
Fixing the holes is not easy as the hackers use packet sniffers /virtualization to claim ownership of the website.
