I have a situation where someone is trying to sabotage my google adsense account by continuously sending personally identifiable information into the URL to my site. How can I block this or at least detect the random variables they are using?
For example, the variable name could be ANYTHING.
mysite.com/?asdfd=emailaddress@gmail.com
or
mysite.com/?gfrewgtr1=emailaddress@gmail.com
...?
The only thing I can think of doing is collecting known variables and then perform a header location redirect to the main site URL.
