Emotional Messaging for Revenue

I was browsing on alternativeTo today and noticed the above message where a header banner should display. The message read:

Hi! For some reason we can’t display an ad here, probably because of an ad blocker. If this ad is not displayed our design gets screwed up. We have full respect if you want to run an ad blocker but we would appreciate if you add us to your white list or consider donating via Flattr or Paypal. The free web is dependent on ads to continue to be free. Thank you, and we hope you find a great alternative!

I like that the website displays character. They know you are using an ad-blocker and are OK with it. However, they request donation if you would like to keep the ad-blocker running on their site. I like the honesty there.

Liked it so much, I actually donated.

More websites should carry this message, no?
