Web Bot to Monitor PHP script

We host a free hit counter service, which allows anyone to get free detailed stats for their website. To get the stats, they need to embed a bit of javascript in each page they want monitored, and within this bit of javascript is a noscript tag that contains a link and link text to a particular website. Most people are happy to leave this link in, since it doesn't even display on the page, it can only be read by search engines. But of course there are always those who will remove the link, along with any benefit we may receive from offering this free service. What we need is a bot to monitor the websites of people using the free service to make sure they leave our link in the javascript embedded in their pages. The bot needs to get the list of active users, then spider their websites and look for the javascript code. If the logging code is present, then make sure that our link is intact. If the link is missing, email the member and warn them that the code must be intact or their account will be disabled. If the code still is not in place after a certain period of time, the member should be prevented from viewing their stats, i.e. locked out of their account until the link is reinstated. After a period of time, the account should be marked for deletion. All of this needs to be done automatically, up until the actual deletion. This is something I have to do anyway on a periodic basis for unconfirmed accounts, so it's sufficient for the account to be marked for deletion and appears in the admin panel as ready to delete. The counter script we use to run this service is open source, written in PHP. So of course you need to have advanced PHP skills.
