Facebook says it has dumped Microsoft banner ads, but what the social network really needs are fewer sleazy advertisers, not less Microsoft.

For example, ads like to one that invites Facebook members to "test" an iPad, Kindle, or Mac that they then get to keep, "participation required."

Maybe you have seen career ads that mention an age, but suggest a job that makes no sense for someone in that age group. Become a cop between 50 and 65? Not likely.

These ads are a natural outgrowth of the pay-for-clicks business model combined witth an "anything for a buck" attitude at Facebook. Since FB doesn't charge for merely running an ad, there isn't much incentive for self-control on the part of advertisers.
