Really freaking mad.

Just have to rant a quick minute here...
I had a 'friend' of mine help out with some code on my website. Turns out before the release of Cryptic he changed all of the adsense publisher id's to his and not mine.
I was wonder why the ads said they hadn't been displayed once in the last several days.

What a jerk!

I had a similar experience once.
An artist asked me to rebuild her website, and a few weeks after I was done, the guy who used to maintain the page uploaded a blank index.html that would redirect to some crappy site of his.

I guess some people are just assholes.

People are dicks.

I get people taking credit for my work all the time, it's annoying when it's something simple that you can't make a fuss about.

Don't rule out the possibility that it was by mistake... if he copied & pasted code from his website to yours he may have accidentally moved the google adsense code as well...

But if it wasn't by mistake, he's a candidate for the biggest douche in the universe...

So ... did you change them back to your IDs and then change your FTP/remote access information so this "friend" has no further access to your code-base?  I'd also have him run a report on the channels he used for your site and get the stolen revenue returned to you.

Also you should report this abuse to Google.  No guarantee they'll ban his account (because it's just your word against his) but it couldn't hurt to try.  They have zero tolerance for abuse of the Adsense/Adwords networks.

I build security measures into my Ad sites to prevent this kind of thing.  I'm not going to tell how I do it, obviously, but it would be very difficult for somebody to "hack" them.

[give in to the dark-side]

Now ... and understand I am in no way advocating this ... what you could do if you wanted to be a vindictive prick and get this guy back.  You now have his Adsense ID/code ... take the snippet of code and drop it on a website with porno.  Once Google sees their ad network on a porn site they'll black-list him and ban him for life.

or just keep clicking his ads, then try with a proxy etc google will pick up fraudulent on clicks and ban his account, they banned mine I wasn't even clicking my own ads.

He won't be able to use ad sense without a bank account on another address
