Incentivising Likes

[Chris.C]

I was just wondering if Facebook or Google+ frown upon offering people incentive to like your business on either Facebook or Google+?

Not sure about Google, but I would think Facebook actively encourages it.

Their like button has triggers you can hook into for when someone likes or unlikes a page.
