OkCupid banner for adblock users

Not sure about it. I have a similar problem - my website http://www.brainleg.com (structural java exception search engine for java developers) is currently supported only by ads, and it is very tempting to put some message to users who use adblocker. Yet as a visitor of a website I would be turned off by an aggressive message like this. Perhaps something more polite would make more sense?

If I saw that banner, given everything that OkCupid has done for me (I am married now, after all), I would donate the $5 instantly. This is a smart response to a user that some companies would see as the enemy.
