Has Anyone tried this?

Non-ad earnings is a feature that lets visitors pay $3, $5 and $10 to your site through our Publisher Support Service.
For every 2-10 visits to your page, visitors will see 1 message asking for support.
After they’ve supported your site, they won't be asked again for 6 months.
During this 6-month period, visitors who make a payment will also see one less ad per page on your site (typically the last ad on the page).

Kinda like begging
