I haven't seen this before. I've got a 468x60 unit below the first paragraph on the page, which has two regular ads with title and description. Those I want - those 2 ads.
Now there are 4 additional links showing up underneath, left justified and just to the left of the little "Ads by Google" logo. - not regular ads, but (JS) text links using keyword phrases as anchor text.
Those I don't want; besides, if that's what the 468x60 will look like, it should be indicated in the Adsense interface. I feel like I've had a bait and switch pulled, and that I'm being spammed with text links by Google Adsense.
