Advertising isn't frowned upon (that would be shooting themselves in the foot, wouldn't it?) but too much in-your-face, over-the-top, never-mind-the-content-here's-the-ads type placement is obviously some kind of quality signal.
The key is to make your site appear to be a useful, interesting and engaging site that just happens to have a few ads rather than an obvious push for money that just happens to have a little content.
My policy on ads is similar to my policy on jewelry - I put on whatever I want, and then take off one piece before I leave the house, so I know I haven't overdone it.
