Now it could certainly be argued creating sites specifically for adsense is against the TOS, but check if its this product you are seeing ads for: its not fraud. If however you are seeing ads for "click my ad and I'll click yours" type programs, thats fraud.
If you do write, please use the subject line "ATTENTION ADWORDSADVISOR - click swap - by request"
And if you'd rather not send it from your account, just use the 'Contact Us' link in the Help Center: [adwords.google.com...]
Thanks in advance!
